I see many Yasuo hate threads that bring up his playrate ban rate or any other statistic but what about 
who all have much higher ban rates than him? I mean Leblanc has almost double his ban rate yet I see no topics about how op she is. I would much rather fight a Yasuo in lane then Syndra or Leblanc to be honest.
Elite4Runner3 votesI think most of the people who hate Yasuo only ever play against him and don't ever actually play him themselves.
Understanding how Yasuo's kit works makes him much less intimidating.
Countering Yasuo has much more to do with understanding his ranges than anything.
Limmie1 votesI'd say most people hating Yasuo played with him on their team instead.
Elite4Runner1 votesI`d say most people hating Yasuo played with him on their team instead.
Then they were either playing with someone who doesn't understand Yasuo yet themselves, or they are a glory hog tryhard.
I mean, those are the most likely reasons for disliking someone who is on your own team.
oSEXYPLATYPUSo2 votesthere are certain champs no matter what the community will cry over....
yasou is one of them
vayne is one
riven
cait
and so on
EndlessSorcerer2 votesMany of them are relatively recent bans or overtuned.
Yasuo has had a considerably high ban rate for months.
RlP K0BE1 votesThat's understandable but so have champions like yet I see no topics begging Riot to rework him. I understand that Yasuo may be frustrating to play against for some players but there are other champions who have been very strong for awhile yet they go unnoticed.
EndlessSorcerer1 votesYou have to consider that Yasuo is frustrating to play **with **for many players too.
Yasuo players tend to play aggressively and lack fall-back patterns in lane (i.e. ranged waveclear or farming, reliance on building damage early), so they can easily feed horribly and tilt into oblivion.
Considering how badly him being picked can screw over team compositions and his player-base's tendency to tilt and rage, it shouldn't be a surprise that many people don't want him on their team.
Honestly, I am just happier when he isn't in the game for either team.
Slythion2 votesToxic Gameplay is often mistaken for being "OP" which is why even when Yasuo is in a sub-optimal position for the meta he's still hated and called OP. He does a lot of stuff (even when it's no effective) and when you spam stuff like that people assume you're op.
MagicFlyingLlama2 votesBandwagon. Most of the people crying are just crying to be heard and have no idea what they are actually talking about. This applies to a lot more than just league balance.
RIP 2016 election year.
