Yasuo's balance is similar to Genji in OW

Genji is obnoxious and is in every match

this isn't because he is OP numerically or even by inherent design. It's just how much he excels at the nature of the game, a 100 FOV shooter.

Close combat action will be very powerful in a shooter with relatively high health bars unlike in CSGO where headshots instant kill people, and where 100 FOV is the standard setting. Ironically, Blizzard kind of understood this and the exact opposite of Close combat, Widowmaker was broken for the first few months in the game, because it was at the other extreme end of the spectrum and "had" to be strong to compensate for using long range in a Close combat oriented game, but that was later fixed.

Genji dashes around like an annoying fly with his double jump, and shotgun right click, which gives off the illusion that it takes a lot of skill, when it really isn't as hard as it looks like. The moment he even touches a person in a teamfight and that person dies, he gets a reset on his dash which goes 200000m and goes through people, which highlights his strengths in a close combat 100 FOV shooter. The amount of skill that a medium or long range character requires to kill Genji, is vastly disproportionate to the amount of skill it takes for Genji to press 2 buttons, aiming a headshot at a butterfly is VERY difficult even for experienced players.

He is also given the standard design of a defensive ability since a (relatively) melee hero who isn't a tank needs some sort of "gameplay induced" defenses. His reflect is on the same mechanical principles of any other shield in an RTS or shooter, though it has the bonus of reflecting damage back. In high level play, this is basically a 2 button window of "do not shoot me" and relative immunity with a few exceptions. The only part about Genji that might take immense mechanical skill, is using this ability as an invulnerability window to gap closer or disengage tool, or even aiming something like roadhog's ult reflected back to another target for a environmental kill.

Yasuo is extremely similar to genji in Overwatch. He is an obnoxious highly mobile hero that excels in a game that has steadily seeped it's way up to being a game of mobility, and the reverse power creep of "Turning everything into a skillshot" has only benefited him as few point and click CCs still exist in the game that are reliable enough to pin him down. Seriously Riot the whole "I juke and dodge shots wow so fancy" isn't as MLG big plays as you think it is, especially when it has a low cooldown and NO cost. Drop that pretentious crap. Everyone in the game is capable of juking, but it's even easier on people who have built in mobility at low CD.

Tracer has the exact same survivability tool of being hard to hit too, however she is actually balanced because the moment anyone touches her, she is DEAD.

Then his wind wall which is a giant "Fuck you" to every mage in the game, which is kind of similar to genji's reflect. He only presses 1 button on his part, while the mage had to line up a variety of factors such as line of sight, cast time, and positioning. Again, disproportionate skill comparisons. Yasuo fanboys argue that "it takes skill to read enemy moves to predict when I should press my wall" and this is true, yet that decision making ability is applicable to EVERYTHING IN THE FUCKING GAME. It's on the same skill and "juke" level of nocturne or sivir pressing their shield to block something, yet his wind wall is MUCH more powerful since it is AOE and is capable of intercepting multiple instances of damage.

There are not enough mechanical gameplay counters in this game for Yasuo, similar to Genji. In Dota I have ghost scepter if PA jumps me which is VERY cheap unlike Zhonyas' in league

I guess the standard solution is to gut Yasuo numerically to "compensate" for how strong he is mechanically, but that really is a copout bandaid fix that will hurt the game in the long run.

I think you need mechanical improvements in how you can pin down high mobile heroes with gameplay.
