Keep whining about the yasuo buffs, whatever, all of bronze/silver/gold/ players are trying to judge if a change is good or bad, what is your knowledge or experience? It's none compared to people who play this game for years. But you keep complaining: "oh nuuu, yasuo buffs, rito why do you buff this noob champion omgggg, it's annoying already". Learn how to play against it, this matchup takes patience and it's about being careful, lol, but of course people are trying to fight with him alone and then they are surprised with the outcome, oh wow, yasuo killed you, how is this possible? You are a mage with ranged spells and 3000 burst, when a bruiser which needs to come close and block your spells (often in a short window of reaction time) kills you it's just so overpowered! He's supposed to die in 2 seconds and stay at 47% winratio, that's his purpose, right?
Honestly I doubt any of you have ever tried to play yasuo in his current state, ANY buff will help him get back to the game, right now he's just something like weak Singed, running around (if you don't know how to walldash you're dead most of the time) and trying to escape every fight in early game. Later he just needs to wait for an opportunity to get into the teamfight, most of the time if you try to initiate with yasuo you'll just end with being oneshot'd by anyone. Until you get 3 items (if you run the classic dd-ie-frozenmallet build) you are literally dying to everything unless their teamcomp happens to be focusing on skillshots/ranged attacks(or spells). You can survive if you manage to knockup many enemies but it's about skill and even tho yasuo's ult isn't a big problem, it's just 1-2 seconds of a knockup - easy to run away if you don't die from the damage, and trust me, you won't.
With the changes to him which were made before he's barely playable, I get better games playing as Riven than yasuo even though I don't play Riven too often and I used to play yasuo a LOT back then, I literally know everything about this champion(yasuo) and I'm an average Riven, yet still I manage to get better scores on Riven than on yasuo. Both champions are about skill (if you are good you will win), somehow one of them is working worse than the another in any scenario.
Is this balanced for you?
Keep your opinions, Riot finally are starting to make good decisions for changes in my opinion, but it seems that your League streamers disagree with them (I've seen someone mention "TOO MUSH DAMAGE", I heard it somewhere before), so you just take their words and spread this b...-t everywhere, instead of "doing your own research" and trying to play as yasuo. Good luck with that. Maybe after buffs something will improve finally - right now the buff is totally deserved. Compare yasuo from old seasons to this season right now. Can see the difference?
