If she is so flat out OP, why isn't she a perma-ban?
I mean.. typically perma-bans tell you who are the current OPs in the game.
Also... I strongly suggest playing her. You'll quickly learn what champions make her life miserable.
But with all that said, I think she does need a nerf. They need to nerf her W shield which makes her a bit too tanky. Maybe nerf her base health/level as well. But Riot is only nerfing her Q damage which really doesn't go at the main issue that she is simply a tad bit too tanky for her role. Is she overpowered though? Nope. I can easily counter pick her if I needed to... I just never had to do it in ranked yet.
