Animation delays tend to just cause anti-fun situations, ("I pressed the skill before I died, why didn't it go off!" or "I want to chase and kill the enemy, and this ranged skill may kill him, but if I use it I will be unable to chase him due to the cast time")
Really, I liked the diana nerf. I think we need more changes like that. I like having a dynamic game, where the 'best champions' are always shifting. This happened a lot during Season 1, and I think that the reason for that was because FoTM champs lasted for literally a month before seeing some change.
Also, mobility needs a nerf after flash changes left some champions with nothing more than a 400 range blink.
