Anivia needs a bug fix
The amount of times I threw out a Q, hit an enemy and the game doesn't register it is too many to count. Sometimes it even triggers my Arcane Comet or even damages them but doesn't stun. And I've checked, they don't get a shield or have anything that prevents them from getting stunned. The game is just weird.
Also, the targeting outline for the spell before you cast it is very inaccurate and the orb doesn't even fly over that direction. The area of effect on the spell is smaller than the spell says it is. Honestly, I can hit enemies easier from spawn with Jhin's ult than this
