Regarding the loot box related changes...
Seems like, at least in the USA, loot boxes are considered a risk for society (for their addictive component). And that is the main reason Apple imposed these rules to specify the drop rates. Which is fine, I think that is good.
But this could be the perfect opportunity to implement something that players have wanted for a long time. The possibility to get a specific champion.
Be open minded and indulge me in this:
Crystals acquired by shards no longer random, no longer spinning, no longer crystals!
Just use the shards to go for your desired champ, with a 50% cost decrease on the second purchase (i.g: 15k for Blade if you don't have it, 10k for second Blade the second time around).
Crystals would no longer be purchased with units. You can, however, get them from completing content (whole crystals), and those would be totally random, perhaps with better drop rates.
Everyone would have the god tier champs? Yes.
Would we have a healthier environment that would prevent the player base from falling into financial ruin? Also, yes.
No one would have the trash tier champs? Most likely they would get them from a random crystal.
They could make it more interesting by raising the cost of shards for new champions.
Of course they could also sell exclusive champions in the unit store. No gambling there, you get what you want.
In other words, it would be great to remove the gambling aspect from this game, completely and change how shards and crystal work so we can have a healthier hobby.
Another idea, could be getting shards for a specific champion (like TMNT Legends used to have), Let's say you need 20 Blade pieces to form one. And those can go to your item storage. Once you collect all the pieces, a new champion is formed. And you could get these pieces randomly playing quests and arenas.
So let me know what other ideas, suggestions or corrections you would make to the game to take the gambling out of it. I know this will not be popular, as people like to have a rare champion, but diversity would still be there, so it will not depend so much on luck, but on strategy.
