Windwall is a good ability but not on Yasuo

There is soo much thing that Windwall is not suppose to block such as Seismic projectile, like Braum R, Poppy R, Lissandra R. Aswell as controlled units like, Orianna Q. Yasuo does too much damage for having 2 defensive abilities, like his Shield passive, his Windwall. And on top of that you could say that he has aatrox lifesteal W, because his Q applies on hit effect. Lifestealing is a defensive mechanic. He is the only champion who can abuse Lifesteal with Warlord on top of being a crit based champion. Lets be real Windwall on Janna would be a great idea. Technically she is a goddess, yet her tornado isn't comparable to Yasuo Tornado.
