Can we nerf Fizz?
The nerfs won't enough, he's still too strong. His R change should be reverted, his E CD increased and his Q range shortened.
He shouldn't be able to kill AD carries.
He's a trickster based champion which means he should only be able to kill low health enemies. Perhaps change his ult to something like
50 / 100 / 125 (+ 15% / +20% / 25% missing health)
Increase the CD to balance it.
