While this IS kind of me just being super annoyed about my last game, this shouldn't be a thing.

You shouldn't be able to have a full team build around one person who can just press R and delete everyone. There are just too many champions(and a lot of them who can hit multiple people) in the game with knockups for Yasuo to be built around, but when a whole team of people outside of an ADC builds with knockups in mind, there's no counterplay. Sure you can spread out, but someone's gonna be 100-0'd unless everyone plays perfectly and all the Yasuo has to do is point and click press R to delete someone. I'd say I'm a pretty fair person when it comes to Yasuo, I don't think he should lose a lot that people claim he should, but there are two things that should not happen in my mind.

1, People shouldn't just be able to press R and get a kill when someone knocks someone up. It's also too hard to aim AT the Yasuo because when a team is actually BUILT around him, you have 5 people all in the same area and can't see who is who with all the glowy shit going on around you so exhausting him is impossible, unless you get lucky. Make him only be able to ult off of his own tornado, please. Compensate him by making his tornado literally his Q with a 3 second cooldown for all I care. Whenever a team is built around Yasuo it feels like there's nothing you can do, however when one isn't built around Yasuo, it's actually a test of skill for the Yasuo player. I don't think Yasuo should have a situation where it's practically a free win if you have a Malphite, Rakan, Gragas, Yasuo, and whatever ADC teamcomp, but I'm not gonna say that he couldn't get compensation for removing this synergy. If he does get compensation it definitely shouldn't be damage though.

2, His wind wall should not protect him if it's in front of him and the shot comes from behind him. It's a bug as old as time and needs to be fixed. His Wind Wall should be designed as a split second block ability, not an "Oops I just got hit by something better wind wall". Yeah sure, collision detection is weird, but it shouldn't favor that situation, even if it is only visually. Either make every projectile in the game visually match it's hitbox, or fix the collision detection on his wind wall, please.
