Kat pisses me off
Give Kat mana or energy costs or something. Make it so that she has to spend resources in order to 100-0 the entire team.
A champion with INSTANT 700 range gap closer with free resets and free manaless pokes is extremely toxic to the game. I don't care if you have one CC or not; her QWE does more enough damage for the ult to even matter.
from game, problem solved. Once you hit her with something, its GG for that bitch.
