Yasuo is not really unbalanced/OP, I am just tired of playing against Yasuo.
Or playing with him on my team. I don't play Yasuo myself because I find him to be really boring, despite what the majority of people think.
With that said, I got tired of people picking him at all times, on every situation, against any champion. I don't know if that is common on NA, but on my server, people just pick him without caring about many important things, for example: if the team needs a tank, or if the team needs an AP champion, or if the team already has a squishy melee carry. And more important, if the team actually has knockups to make Yasuo work during late game.
But no, people just pick him on any situation, without really caring about what will happen. Yesterday, I was playing Cho'Gath on a normal draft, and the enemy picked Yasuo against me. I mean... What the hell? Cho'Gath is a strong counter to Yasuo. In fact, I stomped him on lane. Why would him pick Yasuo? Just for the sake of playing this champion?
The lane wasn't fun, because it is still a Yasuo, but I still managed to win my lane nonetheless. I am not saying that Yasuo is OP or anything. In fact, he is surprisingly easy to counter and unless there is more than one knockup on the enemy team besides Yasuo himself he will fall off late game because he is very dependent on the team composition.
But he is still a very unfun champion to play against, due to his opressive laning phase (contrary to the popular belief, Yasuo's early game is NOT weak, especially since it's on the lane phase where he can take the most advantage of his mobility with nearby enemy minions), ability to scale super well and snowball easily, being resourceless, and having a wind wall that is capable of blocking even ultimates.
And worse yet, people don't know the appropriate moment to pick him. They just pick him without caring about the circunstances. Once I was in a ranked game, and despite the rest of my team trying to convince one of my allies to pick a tank, he didn't care about what we were saying. He just picked Yasuo, and against a Maokai. He surprisingly won the lane - but unfortunately, he was completely useless during the mid/late game because he was squishy and was lacking in utility. Also, our team didn't had the needed knockups to make him work. We lost because we didn't had a proper tank that could start teamfights.
This happens to me every time. I am so tired of playing with a Yasuo on the game, that I started to dodge on normal draft games, whenever there is a Yasuo on either team. On ranked games, I don't do this for obvious reasons. So I just counterpick him with a champion that can stomp him during the lane phase, such as Cho'Gath and Fizz. Or if Yasuo is on my team, I pick champions with knockups, because I know that nobody else will do that.
What needs to be done with Yasuo to make him less of a feast and famine champion that is unfun to play against and more of a healthy champion that can work and still scale well and be really fun both to play as and against?


to be extremely fun, but I rarely use him at ranked outside of jungle or when not being a counterpick in laning because when used as a blindpick in lane he will not give me the best chance of winning.
support come in and steal all your kills and cs?
he can be incredibly easy to manipulate through. Manipulating the minnions in the wave or freezing lane putting you between him and his own minnions annie's the best example of this to a yasuo or just knowing that him dashing to you for his knock up is like a slow motion malphite ult that you can bait and flash repositioning yourself well able to land any close range ability ult what ever and he can't dash to you to get away and becomes totally out of position
