Playing Lux into Yasuo
I'm looking for tips on playing Lux into Yasuo. Of all of the common midlane opponents, Yasuos (specifically, machanically-sound ones) give me more trouble than the rest.
My general laning strategy is to abuse early, since Lux can trade well with her passive, especially against melee. Yasuo makes it a little harder to get mana-efficient trades unless you pop his shield, so I will try for an AA+E+AA combo to poke. The really aggressive Yasuos will jump on you and start the outplay-or-be-outplayed game, while the defensive ones will wind wall. In short, early game trades are more difficult against Yasuos (for me) than most other champs.
That's fine, of course, but I'm looking for tips to play against him better. Once we hit 6, I pretty much submit to the reality that I won't kill him without a hard CC gank, and I also can't push the lane safely unless I know he has gone back or roamed, since he can just jump on me at any time and murder my unborn children.
TL;DR - Yasuo is hard for me as Lux. I'm bad.. help me stop embarrassing myself against this very skill-reliant champ.
