Why Yasuo is cancer

Yasuo is an obnoxious character who dashes around for no cost at a low cooldown and charges up free defenses for doing so

The average bruiser top lane shits on him, no one denies this even in the lowest elo. He frustrates mages mid, especially immobile mages because of his "unique gaem dsogen mobility"

The whole frilly set of movements gives off the flashy LC$bigplays illusion of "high skill cap" character. But in reality it takes zero skill to do so. Wind wall is instant and can be instantly panic mashed to "clutch mlg big plays" cockblock skillshot based abilities that take a disproportionate amount of skill to properly land and aim vs the amount of skill it takes for yasuo to "counterplay" it with his windwall.

This entire concept of being a little bitch and wasting enemy abilities missing you on your high movement low cool down dashes is reminiscent of old Phantom Lancer in dota. Phantom Lancer's unque trait was that he would make illusions of himself that would fool enemies into wasting entire ults onto him, thinking that it would be him. His actual right click carry damage was kind of below average, though it did mana burn. In this way he would carry by making the enemy waste resources. Normally I think this is good game design, a conceptually creative way of carrying but that is a game with BKB, forcestaff, and tons of immunity abilities and items to shit on carries.

Yasuo is a nonstop mobile character in a fighting game where mobility defines everything.

Though I will admit Asymmetrical lane matchups shouldn't especially be a basis on actual balance changes, as well as going yasuo mid always means an AP jungle or top, otherwise your team comp has no magic damage and the enemy team stacks armor and facerolls you. Thus we can conclude that the majority of GD whining about Yasuo is from solo Q where there is zero coordination.

The reason why mages mid complain about Yasuo and not Zed and Talon? Zed and Talon run on resources and don't get free defenses. Their mobility is also on a much higher cooldown and actually costs a certain amount of resources, in which zed's case, makes it easy to telegraph when they will use it.

Yasuo takes too little skill to "mlgoutplay" most mid lane matchups

"I move and get free defenses" isn't gameplay Riot, not when there is a giant area for him to walk around in lane, and unlike in dota where mid lane has highground and harder fog mechanics that make lane harassment an actual timed decision.
