All the champions that you guys complain about all have a below 50% win rate
Lee Sin : 45% Nidalee : 46% Kalista : 48% Zed : 47%
I know win rates aren't everything but if a champion is so OP, why is it that they lose more then they win consistently? Each one of them is played well over 500,000 times each month. You'd think if they are so OP, wouldn't they be winning more then losing? And by a significant amount? Heimerdinger has a 54% win-rate, and don't say he isn't played a lot because he has well over 200,000 games played each month. Thats more then enough games to know that he wins consistently by playing Heimerdinger.
So screw all your QQ threads about Zed, Lee, Nidalee, Kalista, being OP. They aren't really OP just for many people they seem annoying to play against and jump right on to the conclusion that they are OP.
