Latest patch broke Anivia to the point she is unplayable
Before the patch hit you could cast Q with either a double tap or tap then left click and now its 50/50 if it works with either choice of casting this ability.
Just lost a game because of this bug as every time I tried to throw it into a team fight, I would just be standing there doing nothing while I spammed both ways trying to make Q cast (it wasn't even lag, my ping was ~90 as usual and before this patch I never had this issue).
I doubt this is lag related, I assume it's from the new changes to Anivia with the cast lines confusing the game controls (like how for example Cho'gath's is Q and then left click).
Until this is fix'd, RIP Anivia
