Yasuo is too OVERPOWERED!

I was playing a game with Kat vs. a Yasuo and that guy literally killed me in 2 abilities after unlocking his ult (he wasn't fed, he had 0 kills). I hope RIOT nerfs him in the upcoming patch.

Well he has tons of dmg and when you are a squish close caster he is going to optimize his knock up/ult
He killed you, so he's overpowered?
Wot?
Yasuo needs a serious nerf. He is almost impossible to go up against. His shield absorbs WAY too much damage and should at least cost something. He is seriously the most OP champ in the game. I can't stand playing against him. It almost makes the game not fun anymore.
