I have just realized there's actually something good about playing against a Yasuo.
And it is that you are 99% sure you will end up reporting him because either he will spam "ez" in the chat, or insult his own team, or start feeding because he considers his jungler isn't camping the lane enough, or throw the game jumping 1vs 5, or go AFK "because his team doesn't follow him when engaging" or anything else. At this rate it seems that you are not a real Yasuo main until you follow every single step of the toxic behaviour.
The only rewarding part of having to deal with that pain in the ♥♥♥ for 40 minutes is to unleash the frustration you have generated via reporting him.
So go ahead guys! :D Now that you have the key to enjoy Mr. edgy samurai's existence, you can go play and reduce your average tilting per game. Enjoy.
