lol "balanced" i play her so much and get fed that she is a pub stomping no brainer. honestly, she is so easily to abuse it's not funny.
There are few champions who can set her back but i think when the new runes come out she will get a bit weaker.. wait for the rune system and see how she takes it then because the new fervor is a disadvantage to her now over the current one because it loses stacks and she procs vitals in team fights on other people so she'll lost her damage a long with it being harder to stack up..
she is still overloaded thou so a few tune down's wouldn't hurt in my opinion
