Played Aurelion Sol into Yasuo (Blind pick)

Does his windwall block your stars?

You really shouldn't be losing that lane, he can't block your DPS and you have lots of range for relative safety

at worst you should be able to stagnate it and farm

Aurelion is one of the weakest mages vs assassins like him, I don't think you could have done anything..no matter what he's going to get close to you. Your ult can only do so much on that long of a cooldown. Your Q is pretty slow and you can really see it coming, it's not like he can't see it and put a windwall up and without your stun you can't hit him with your W.

Aurelion can trash yasuo if you play safely, get ganks and wait for him to overextend. Most yasuo players just go ham, and baiting their wind wall is very easy. Not an easy lane if you are not experienced with it, or against a rare actually good yasuo player, though.

passive/W/R ignores wind wall, only Q is blocked. Q cooldown is a lot shorter than windwall, so you can bait him.
