One For All!
I love the One For All game mode!
I have however found it really difficult to tell my teammates and enemies apart which seems of some vital importance in this game. If we are a Blitz team (for one example), I want to be aware of who might be building tank, who might be building AP, and who might be building AD to better position ourselves. Currently if you happen to not play that champion at all or much, you will probably not have skins for them which might lead to bad positioning repeatedly.
I have just found a lot of confusion in that game mode some times that possibly doing the unlocking a random skin thing might help. Been thinking about it for a while. Just an idea.
Love what you do!!
