Almost every single recent rework or new champion has followed a specific pattern:
- The champion is released.
- The winrate is on the lower side - to be expected for a difficult or unexpected change/mechanic.
- The balance team freaks out and buffs every part of their kit through the ceiling.
- Once people learn to play the champion, they break the game, and the champion becomes horribly unfun to play against.
Just look at the stupid fizz buffs, for crying out loud. He's topping the champion charts in diamond already. It was a complete overbuff and we'll have to deal with it until the next patch or hotfix.
Buff in moderation, please.
