hey there.
I have a simple idea that would be super cool if added to the game.
make new costumes for the good characters or all of them and then be like " win X fights with this character to unlock this skin" and you can be like only war fights or aq or questing or arena or all of them but arena would be so easy for those who grind a lot to get all the new costumes for all the characters at the same time. but in aw or aq you only use 3 champs and the most number of fights you can do is 7-8 I guess so be like win 8000 fights in aw with this character to unlock a new skin.
this idea came to me since I saw the awesome evil king groot in the infinity quest and the amazing Hyperion !
and if you wanna make money out of it you can make special costumes that can only be purchased
effects can be like glowing aura or something
thanks for your time
