That windwall has an absurdly long cooldown. It's not hard to bait out most of the time.
Windwall doesn't "totally negate champions" as you claim. It does change how you have to play your champion, but it's just another ability you would need to play around, similar to how you would play around Ashe having her ult, Veigar having his cage, or similar utility spells that the opponent can have. Veigar having an on-demand AoE stun, or Ashe having a global stun doesn't negate champions any more than Wind Wall.
The argument of Yasuo putting his wall at a distance and standing away from you to negate abilities is pretty weak. Any ranged champion can negate your abilities and still deal damage simply by kiting, they don't need a wind wall. Yasuo can't even strike back through the windwall from range unless he has his 3rd Q ready, or a teammate of his sends you airborne.
He's hard to come out of lane ahead with, and just about anyone can shut him down/zone him. If you're really afraid of the matchup, try someone with low cooldowns or no projectiles, such as Annie or Malzahar.
