His crit has nothing to do with why he's strong, it's his ulti's buff. Due to it, he's getting a free LW without any drawbacks. Even turning tank items into a much better LW. Crit has a drawback of needing crit AND he still gets a debuff for the crit, but his ulti's buff can literally have an uptime of at least 50% since it's duration last almost as long as the rank 3 ulti CD is.
Yasuo would be fine with just an ulti rework, because then tanks could actually stop him from doing what he wants but he could still be a threat. But atm, tanks are useless vs a late game yasuo who could just focus them and ignore the rest of the team.
But for now, just buy ninja tabis and if a tank grab omen, and try to pick him off. Yes his inf dashes has become meme worthy but it's pretty predictable where he's going to once you calm down and focus on that he's simple. Teamfight-wise try to bait his wind wall then your tanks won't get locked away from your team for him to just outright kill.
