INGAME BUG
Kayle
(W) heal is half to allies but in the tool tip of the spell dose not say anything about that, not sure if its a bug or you guys haven't update that.
Amumu
amumu's ult say that renders then unable to attack or move, but some champions can still use abilities like jumps and flash, spells that are like amumu's ult on othere champions like swain
(w) don't let them use them, not sure if i am right on that one but i don't think they should be able to jump away inside of my amumu's ult
