Something needs to be done about Yasuo.

In S5, I started playing Yasuo and thought he was a really fun champion. Yeah I am aware he was obnoxious then but he was still able to be dealt with. I got pretty competent with him and played him if I just wanted to enjoy myself but now with how strong he is, he's not even fun anymore. In S5, I've gotten pentas with him but never 1v5'd. In Pre-S6, the second game I played as him I just stood in their base taking towers and anybody who got close died and they literally could not stop me. I had an IE, Shiv, and vamp scepter and was able to 1v3, then 1v5, then 1v5 again and end the game without my team even being there. I play this game to have fun with my friends and work as a team but if I can just do everything myself without need for anyone else's help after 2 full items, then what's the point of even playing him? He's too good to the point where he's not fun to play against or play as.
