I just played a game with and against her, and I feel that her early game damage is way too much. While I was playing her, I was against a kha'zix top, and by level 3, I was capable of 100-0 kha'zix. While playing against a Poppy as Rengar, my level 2 was out damaged by her, which is absurd, as Rengar has one of the strongest pre-6's in the game.
Also, I would like to mention, her W is essentially an Azir ultimate... how is that fair in anyway???????
Anybody care to share your ideas?
