Yasuo is not OP, but the people that play him are just so negative.
My last game I got a Yasuo who fed the whole laning phase and then afked after one constructive comment hit him. I don't know why every single Yasuo I meet is like this. Is there something in his lore that says you have to be toxic to play him? seriously, I really wanna know why they are all like this
So you see a flamer playing yasou, now all yasous are toxic to you..... Flamer plays sona, still flames but now sona is not toxic, because its not yasou
YASOU is not a reason to be toxic toxicity comes from a person
Damage-oriented champions focused on flashily "outplaying" opponents (i.e. Yasuo, Riven, Vayne, Zed) have a greater-than-average tendency to attract toxic players.
They seem to appeal to "selfish" players who focus more on K/D than team cooperation. If they aren't performing well personally, many of them just stop caring about they game since they aren't in a position to carry it and blame others for putting them in that position.
I made the same type of post just a few minutes ago. 5 downvotes and a comment calling me an idiot.
for some reason most players who use champs that are OP/low skill that have high mastery with said champ....are generally toxic....includes stuff like

I think that this tends to be due to the fact that since they have such a low skill floor and can hyper carry, when they do the players tend to think that they are better than all of the other players. A lot of yas players aren't toxic though, so keep that in mind too!
Hey there friend, If you truly believe all yasuo's are toxic, mute them all before a game starts. Problem solved yw :)
I'd say a lot of the "try hard" champions: 
All tend to invite that toxicity. "Hey I just outplayed you so I am justified in being the biggest douche%%%% for the remainder of the game.
I will say however that it feels better than sex with you simply wait out the game and finally demolish them and laugh on their corpse as they flame you.
= OP
Agreed, somehow this champ attracts toxic people and I'm not sure why.
lol I mute every Yasuo player (mostly are 13 years old kids) everytime I play in garena (SEA) server since they're toxic af. If you don't hand them mid, they go afk and say things like "I fuck your mother".
