Upvote if you just don't like Janna and her immunity to nerfs
http://lolalytics.com/champion/Janna/
with a win rate much higher than Lee Sin's (53.64%) and seeing how obvious it is that Lee Sin needs nerfs, I think it's even more obvious Janna needs nerfs. She's been busted af, and is the best champion to play if you want to get carried. She also counters the champions I play, and I don't like it. Since I don't play her, I suggest that she is not just nerfed, but gutted. She's been top 5 solo queue support for more than a whole season.
