What Is Yasuo

There's a lot of mixed ideas between Yasuo being broken and not. Or easy and being incredibly hard. This game I was playing Aurelion Sol, no I did not feed because of the Diana, Yasuo, or Akali. I got first blood because I know how the champs work. When I switched lanes with Lee it was incredibly stupid laning against Yasuo. Even though my teammates got a couple of kills on him, he scaled INTENSELY. IT WAS DUMB. I know how Yasuo works, but really, I have to give up farm because I don't want to give him a buff from his ult. I get that his two Qs are the condition for his ult but its not fun at all. Having to back up everytime you see his Tornado particles is stupid. It comes up every 10 seconds, and even if he doesn't ult, it pierces, crits, and does a ton of damage after 15 min. Also, why does the whirlwind last 10 seconds? Its the (old) Rengar equivalent of keeping your stacks as long as you wanted. I want someone to share a replay of them playing Yasuo without using ulti. Because its possible with his critting, low cd, no cost, ability, and ranged auto attacks.

I got countered. Pretty salty atm.

Does Yasuo need a buff? I've seen players with that name.
