All The Yasuo Hate on The Boards Will Accomplish Nothing
So there has been a trend of hating on Yasuo players/champion design/overpoweredness/everything on the boards recently. Here's one example: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/PpAejolU-a-message-to-every-yasuo-player-sincerely-a-casual-league-player
There's just so many things that are wrong about this.
First off the degradation of Yasuo players that has simularities to witchhunting. Sure, Yasuo may be annoying and a bit overpowered right now, but that is not the player's fault. He just wants to have fun playing Yasuo and appearantly that makes him an asshole and a terrible human being. Also, some things mentioned there are just not true. Not "every Yasuo player" spams mastery taunts ( what's wrong with that anyway ), is overconfident and starts 1v5s, and claims that Yasuo is super underpowered. Sure there are some but that is not caused by playing Yasuo, Urgot and Yasuo mains alike can be assholes.
Next off it's the fact that he and other Yasuo haters complain about him being OP without actually doing anything against it. What are you guys gonna reach with those posts except being angry on the Internet about a character in a video game? If you want it to change, try to talk in a more reasonable and civilized tone, give actual suggestions on how to make him balanced, do some research and give valid arguments to show that you are serious and hope that someone from the balance team sees it and thinks about it. Just like this guy did: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/Xd2GopFL-how-to-fix-current-yasuo-6000-yasuo-games-diamond-2
This has been a trend for longer that some people might think, we had Tank Ekko, Vayne, Riven and a lot of other champions that made people get angry. In the case of Ekko for example 90% of the threads talking about him didn't reach anything but creating unnecessary spirales of hate. But there was that one guy who made the suggestion of making Ekko's utility scale with AP instead of it having high base values, he did it in a civilised way, got upvoted, a Riot employee ( Meddler I think ) saw it and guess what happened a few weeks or so later. Now Ekkos is in a pretty good spot.
Tl;DR: Don't be angry on the Internet, it won't change anything.
