So Riot Hates "Hidden Power", Right?
I think a while ago we had a huge campaign about clarity, and how everyone should be able to know exactly how strong an enemy is without having to main said enemy champion. If I'm not wrong, Riot doesn't want to give any champions advantages that can't be quantified, which is why Annie can't hold onto three stacks of her stun for nasty surprises anymore.
I suppose that's also why champs like
are allowed to have huge disparity between the size of their spell's animation and the size of the actual hitbox.
