My problem with Yasuo

It's not that he does damage or that he is easy to play. It's the fact he is strong all game. He has a good early game, a good middle game, and an insane late game.

The second he hit's 6 your built armor means nothing to him. Meaning he doesn't have to worry about building armor pen until much later in the game unlike most carries where you can build armor if they start to get ahead. Yasuo basically eliminates any chance of coming back. This is completely ignoring his wind wall. If he dashs Q ults you are dead. There is nothing you can do because his dash is linked to your own minions and his knock-up becomes basically a better Riven W that can crit.

At the very least make it so that Yasuo's ult marks everyone that he hits with it with a debuff which has the same duration as the current buff that allows him to use the armor pen passive so that he has to actually get you in the ult to ignore your armor. I feel like this wouldn't gut Yasuo, but would encourage using his ult properly. And this would allow people to build a GA and come back somewhat stronger because the debuff will be gone. It gives Yasuo some actual counter play instead of just eh deal with his raw numbers and insane power curve.
