Yasuo lowest winrate?

I been here since season 1 and the recent nerfs to yasuo made him garbo teir as a champion. He currently has the lowest winrate in the entire game. And please dont talk to me aout worlds when they was on a patch long long ago i'm not sure exactly what patch but dont compare this to worlds please... Yasuo use to be my favorite champion and now i dot even like playing him cause i do poorly like super poorly and when i do good i still feel i'm doing poorly. Like i said a moment ago i been here since season 1 and this is what riot use to do to champions that are perma banned like aka morg amumu rammus back in season 1 they make other champions that out perform those whom are banned to try and shift the meta aka lux came out lee sin with his invades hec and many others that made the game more intresting. What do they do now every champion that gets perma banned in solo que gets the IRALIA treatment with nerf after nerf and then if that dont work they get the kassassdin treatment and reworked.... Another thing talon was nerf another main of mine and all i have left is kat who is extreamly easy to counter and somewhat hard to lane in certain match ups and team fighting with her is hard cause every champion in the game just about has something to stop her so shes been overloaded with dmg to compensate that but lets not talk about her its about yasuo and his current state and how i and probably others who feel he is low teir now... Thoughts???

Its not like hes not popular hes still pick quite often at a 8%+ rate meaning a lot of people still like his concept and probably the fact hes a samurai but still with lowest winrate
