Here's my deal with Yasuo.
He CAN be amazing with a lot of skill, but he doesn't NEED a lot of skill.
When you play as Yasuo you can really pull of some amazing plays, his skill cap is through the roof. I've seen Yasuo's kite around enemies in 2v1, widdling them down and it is quite the spectacle. He can take a lot of awareness to pull of some crazy stunts.
That being said, the skill isn't something needed. His skill cap is high but starts low, similar to Zed, who I find easy to pick up but really hard to master.
