Overpowered champs.

Hi there. I have been having a lot of problems with some of the recently buff champs. I had played a game against a YI not too long ago, from what it seemed he was not very skilled. He missed many of good chances, dive bombing into turrets in horrible times, and recklessly going alone against me knowing I can stun him easily (As Sejuani) and mordekaiser getting a very easy kill, despite all of that he carried his ENTIRE team. His attack's and running speed were very fast, not to mention powerful.

I know this come as ranting, though you guys need to admit that this here is just too much. I LOVE this game and I genuinely hope it grows but many and OOOOH so many things need to be done, starting with NOT buffing easy to use OP champs.

Please reply back and tell me what you thought. Do you agree or disagree? If you do or don't please explain your point in a perspective matter while putting how it effects you and or the gameplay. I will read everything you have to say and put your words into thought.

BTW, should I have put this discussion in General discussion or something else?
