There is no place on the world that this would make sense to anyone other than Kabam. I’m not trying to be funny or disrespectful but why on earth would someone give up 3T4CC for 1 random class catalyst crystal. This literally makes no sense even for end game players.
It makes more sence to trade 1 for 1. No matter where you are in the game

You could be like me and have no mutants worth ranking. I have r5 x-23, gambit, iceman, wolvy, psylocke, cable, and AA. I also have a r3 5* storm, NC, and a r4 5* AA.
I have zero mutant champs that are even worth consideration for ranking. Any champ I would rank, would be to simply spend the build-up of mutant t4cc that I have.
I could sell 3 to try and get a mystic or cosmic since I have fewer of those. It's no loss for me since I wasn't going to use them anyway.

3 for 1 bruh.. lol you will still need them in the future they should've just increased the amount u can hold

I'm not saying it's the best solution but it's better than nothing.
Even if I pull a 5* iceman tomorrow, I can easily get enough catalysts to rank him up before I get the necessary t2a.

As someone that has ranked up champs to avoid expiring cats, I think this is a great idea.
I am by no means an end game player, but I have been in the situation where I have had to face the situation of - spending 5 t1a and 4 t4b's to avoid allowing 2 t4cc's to expire and end up R3'in a 5* I had no intention of ranking up past r2.
I would have happily sold 3 of the t4cc's to avoid spending the t1a's and t4b's.
@mostlyharmlessn , Glad you like it
Pls do share with us once you tried the 3:1 RNG
Do share with you, but trading in your expiring 3 T4cc
do you manage to get the 1 T4cc of the class you need, or do the RNG give you one of the class that you are also overflowing?
Would like to feel your experience since I won't do it myself
Cheers and all the best!
I'm happily waiting to trade in 6 tech t4cc's for 2 shots anything other then tech t4cc's since the game has been giving me an abundance of those.

As an end game player I can whole-heartedly dispute that statement. This is a horrible deal. End game players are overflowing with t4cc. This is just another way to stick it to us it seems. With how absolutely horrible the game has been performing recently I would think that you would start introducing things that are over the top, not whatever this is.
100% agree. This feels...wrong. It’s the typical scenario of one step forward and three steps back with this game.
I’m not disputing the validity of RNG in MCoC, but why should players be penalized 3:1 for poor results generated by the game? No matter how overflowing you may be, it’s a double slap in the face...and then you are subject to the whims of RNG all over again.
Dr. Zola
However you want to characterize it, the "penalty" of resources expiring is a consequence of inventory limits. The limits themselves imply that there's a penalty for not using resources beyond the inventory limit. Players are assuming that anything they acquire in-game is somehow something they permanently "own" and when the game "takes it away" that's a penalty, but that's simply false. The value of the trade isn't properly compared to the value of the catalysts going in, but rather to the enforced by design perishable nature of resources above the inventory limit.
You can say it is a slap in the face that the game forces you to give up three for one, but it isn't forcing you do that. It is allowing you to take three things that are about to have zero value and trade them for something that has higher than zero value. If you're actually trading three catalysts that have actual value to you for the chance at one catalyst with actual value to you, then that's dumb and the player that does that has no one to blame but themselves. It is a slap in the face, but it is a self-inflicted one.

I agree with this statement. It doesn't even make sense for end-game players. Unless you have absolutely zero Champions in your inventory that can be ranked up with the catalysts you possess (even the **** champions can have decent synergies with good ones), the value of a single Tier-4 class catalyst is simply too great to trade three for one random T4 class catalyst.
This is a classic bait-and-switch. You get no control over what catalysts you receive (barring the new T4 class catalyst shard quests, which are garbage; the rewards are so low that it would take you months to even form a single one). So Kabam gives you 5 T4 Cosmic Catalysts when what you need is a Skill catalyst, so you trade in three of them and pull a Mutant catalyst. Congratulations! You just gambled and lost. You had roughly a 17% chance to acquire the kind of catalyst you needed in the first place, and then spent 3 to get a 17% chance to pull the one you need? That's less than a 1% chance to get what you actually need in this exchange.
You're way better off working the catalyst arenas to get the random catalyst you need than wasting resources on this.

It's actually not for end game players because we have all the t4cc we need. personally, even after opening a bunch of crystals to r5 Starky, I still have over 30 full t4cc crystals and over 1100 frag crystals.
IMO, the main people who are goin to go for this deal are mid game players gambling their minimal number of t4cc on the 20% chance they get the class they need for that r4 champ. 80% of the time they're going to be hugely disappointed not only because they didn't get the class they wanted, but also because they don't have a plethora of t4cc to throw away.
How about ya worry about the lag that has gotten me killed 5 times today and not working on more ways to screw people. I wouldnt give 3 for a random 1 if i was overflowing time running out or any situation in this game. Those are just as if not harder to get than t2 alphas. At least i could buy t2 alpha shards in store everyday.

I wouldn't go that far. Lots of people get t4cc easily without spending and if you need one class for a rank up and open crystals it's easy to wind up with a lot of stash cats you can't use. It's not a good deal by any stretch of the imagination but I would've done it a few months ago when I needed one or two mystic cats and had expiring cosmic, mutant, and science cats. Had to let a bunch expire. I don't have that problem now because I can't pull any champs worth ranking and I'd need more than one champ of the same class for it to be an issue.

That's not discrimination. The Feature is available for anyone to use. It's probably more useful for those who have a number of Cats on-hand. That's the target. Many things are introduced with different demographics in mind. For example, the Class Expert Proving Grounds. That's not really for End-Game Players because they have many Cats. Anyone can do it, but the target is for people who need it. Same thing here, different demographic. It's impossible to make everyone happy with one thing, so they do their best to include something for everyone. Some content will cater to some and not others. It goes around.
I'm not an end-game player. I'm a casual and have not a single science champ worth spending a single gold on. Yet the game has seen fit to give me an abundance of science cats that are constantly expiring and I can do nothing with. I am looking forward to trading 3 of them for ANYTHING but science tomorrow. (Even if I pull a great science tomorrow, I'll still have enough t4c's to R4 them as well as r5 a 4*.) Not only will this convert something totally useless into something I may use, but will also free up inventory for me to crack open some of the abundance of alliance, t4, and t4 frag crystals I have been hoarding due to so many t4c expiring. (Several hundred right now, not all of which I will open.) Is it screwed up that inventory is so small and expires? Yeah. It is what it is though.
Personally, I think a far better way to make players grind for and spend resources would be to simply give them good champs. The constant waste of 5* shards on totally crappy champs and dupes thereof creates a deep dissatisfaction with the game. Watching resources expire because you have no one to use them on does also. I've calculated my ****-champ-pull-rate at about 94% right now on 5-stars. No fun. Cracking 5* crystals has become a meaningless chore now. I do not work toward any goal because there is no goal to be obtained. I know with 94% certainty that I will get yet another useless champ that I will never do anything with. Kabam was very wise to make alliances, because if it weren't for mine, I'd have been gone long ago.
I thought one of the points of nerfing all the great champs way back when was so that no champs would be so game-deciding that people would hoard their resources waiting for them. If so, the drop rates of the champs has not changed in recognition of this theory. (Not saying I agree with it.) If Kabam is saying that all champs are roughly equal now, why is not their drop rates also roughly equal? I bet I'll pull Ironman 10 times before I pull Blade.
I'd love to spend these resources, but not on Kamala, Cyclops, Iron Man, etc. 33 out of my 36 5 stars are completely lame and I've only duped 1 of the 3 useful ones. Give me champs worth spending on and I'll happily spend.
Would be nice maybe once a month or so though. That way if I had zero for a champ I wanted, in several months time I could potentially r4 him. I don't think that timeline is beyond reason. I got two of my good champs in a row. They were both tech. I used up all my tech cats for the first one and now it will literally be a year or more before I can do much with the other. I have no buyer's remorse, but I think making a player wait a year or more to be able to rank up any given champ is pretty unreasonable. I mean, what are we doing here, hoping to one day pass our accounts onto our grandchildren? This isn't retirement investing.

While I understand the logic of it, I’m still put off by the mechanics. The very reason there is a need for this in the first place is an artificial cap on the amount of items that can be held in inventory. Why do cats expire? Because Kabam decided they should, like they are tomatoes or something. Why can’t some things be consumed before they expire? Because the other things you need in order to use all the perishable things you have aren’t readily available in game, partly because the folks who manage the overall in game economy have done so in an ad hoc fashion. Hence—rotting tomatoes.
And the trade isn’t for things with > zero value in all instances. In fact, for many it is a trade for something with the mere potential for > zero value. That’s where the slap in the face comes in...you’ve been slapped by RNG once already and your fate is once again in the hands of RNG. I’m sure some will be happy with the results.

One of the fundamental problems is also selectiveness and the Prestige Race. Players have been chasing Cats for years through AQ. That's led to an overwhelming surplus of them, which is bound to happen when you hyperfocus on one aspect of the game. The end result is too many. The other side, the selection side, is that people won't Rank Champs that the majority collectively deem "unworthy". Outside of not having other Resources, that is. There's very little Kabam can do to accommodate selection, outside of what they're already doing. If people Grind AQ that hard, they'll end up with Cats. If they don't use them, they'll end up with too many. The only other option is to reduce them from the AQ Crystals and redistribute them among Tiers, but I fear that would be met with a much larger reaction than this change. Fact is, people can hold on to them as long as they can, but they're meant to be used.
And one more thing: why all the fanfare if this is pretty much just for the smattering of players who are sitting on hundreds of T4c crystals and T4c shard crystals? This is so important a change that it needs to be trumpeted as part of Awesome August 1 or whatever it is?
Why not just meekly say “hey we are throwing a bone to the upper upper crust” and leave it at that? This announcement is quite possibly the most verbiage we’ve gotten out of a mod in a week and it’s all about this? Sorry but it’s a trash option for all but the most rewarded Summoners in game plus those who have been so triple-witched by RNG that 1 for 3 feels like a good deal.
