I honestly don't think hes too op, hes just so fucking annoying to play against. His kit is slightly toxic imo. I also find that yasuo players are the biggest spammers of the mastery 7 icon and also yasuo mains seem to be one of the most toxic and stuck up of the league of legends population atm.
Forgot about 
already? Yes i agree that a lot of Yasuo mains are douchey. But there is always the few that are nice. His kit revolves around his mobility, so i can see why you find that toxic. But i believe if you dont give them a reason to brag about anything and spam mastery then they wont. And try not to let it get to you. Yes i do play Yasuo a majority of my games, but i try to be friendly and have fun. I give out pointers and what not. Just try to have fun and don't let a person who is playing a champion get to you. Remember, there is always someone else behind that champion that you're against.
Yasuo is annoying, but Riven is even more annoying and stronger.
