Hello! I have been playing MCOC for roughly one year now and I thought I would share my account achievements as well as my thoughts on the game at this point.
A few things to keep in mind....
1: I typically play MCOC 2-3 hours per day. Sometimes more or less depending on circumstances.
2: I didn't grind many arenas until the last couple of months. Typically just the minimum rank rewards.
3: I am not free to play. I'm not a whale either though... if I see what I think is a good offer I usually pick it up.
4: I watch Seatin and BrianGrant on youtube a LOT. They both have a lot of very helpful videos and guides that allowed me to do things like Act 5, LoL, and RoL. I seriously wouldn't be where I'm at without them.
First lets discuss my roster:





I'm pretty happy with my current roster... there's no champion in particular that I need to progress further.
Secondly, here are my masteries. After watching a lot of youtube videos this is the setup that I like the best.



To me (correct me if I'm wrong) this seems like a fairly balanced mastery build. getting deep wounds to lvl 5 has helped me a ton since I rely pretty heavily on Gwenpool to clear things like the monthly event quest.
Thirdly lets talk about what I've accomplished over the last year.
1: I have completed act 5 100%. After pulling blade I desperately wanted the generic awakening gem from act 5 so I blitzed through it in a little over a week (lol) to get it. I thought 5.3 was harder but that might be because I had gwenpool to tear through modok and mephisto. Watching Seatin and BG helped me a ton here as they had tips to make it easier. I also knew what champions I would be facing which allowed me to change my attack team as needed.
2: I completed RoL. Which honestly wasn't that hard to do. I used my 4* Starlord and 3* Guilly.
3: First LoL clear. I did this about 4 months ago with my 4* starlord. I ended up using about 2500 units and all of my admittedly small stash.. but it was well worth it IMO. LoL 100% will probably take me awhile.
Here are a few comments I have about problems I've run into and the current state of the game.
1: Gold, gold, gold, gold GOLD!!!! Seriously, I didn't used to have much of a problem with gold... until recently. Now I have to grind arena like a madman for a week to be able to rank up one 5*. I feel like a fair solution would be to increase gold from battle chips as well as questing. I hate grinding arena but I also realize that Kabam can't just hand us everything. Grinding should be rewarded with appropriate rewards.
2: AQ changes (AKA, Sentinels) After going through map 5 with sentinels I don't foresee having much of a problem with them. my gwenpool still rips through them just fine. But what is day 5 going to be like?? I definitely think that the rewards should be buffed. Anytime you increase difficulty the rewards should also be increased. That being said, I think the sentinels will be just fine and people will get used to fighting them.
3: Bugs. There are a LOT of bugs in this game. I understand that you won't be able to fix all of them because it's a multi platform game. That being said, there are some MAJOR bugs that need fixed ASAP. For example, losing control of champions, AI recovering quicker than they should, blocks randomly dropping, getting hit trying to double evade back, ect. These have all been well documented and should be given priority over releasing new content IMO.
Overall I really enjoy this game. I'm in a good alliance that does 5x5 and the rewards are good. I enjoy the challenge of the monthly event quests and occasional challenges like the last boss rush. I doubt I'll still be playing in another year but we'll see

Hopefully you enjoyed reading this. cheers
