Getting counterpicked by a yasuo feels awful.
No other champion takes the concept to a whole new level. If you are playing an immobile skillshot mage against a yasuo you will be completely useless in teamfights because of 1 ability, his wind wall. This ability lasts 4 seconds and has a 9.9 seconds cooldown with 45% cdr. You can't wait out his wall because he will just kill you before it expires. He can make many mistakes and not get punished because of how overloaded his kit is. Meanwhile if you make one mistake against him you are dead.

. If you hit your binding before he windwalls, you can ult off it as his windwall CAN NOT stop Lux's ult. I've counter-picked Lux into Yasuo a few times, works well when you know how to play her. And with her shield and slow on her e, you have a chance to dual him OR escape. She may be squish and have no real escapes, but she's hella strong against Yas.
's ult also goes through the windwall.
would like to have a fucking word with you
