I suck at yasuo

Just because you can dash doesn't mean you should.

Play something else. You shouldn't be picking a champion that ruins other peoples' fun.

On top of that, Yasuo is difficult to learn meaning you have a painful learning curve ahead of you. And he's banned a lot of the time anyway so you will have to play something else a lot of the time even if you do pick him up.

Stop playing him. Don't do that yourself.

Try to learn how to use Q first (not missing it, since it's like 80% of his kit, don't try to do mad skillz E when you start learning him. I'm not a Yasuo player, but when I have to play him (I mostly play ARAM), I'm decent.

Only use your E as a mean to get near the enemy through minions (so that you understand the range / how it works), don't try to get the 100% crit asap, you can start with a doran blade / even a long sword into a vampiric scepter. First item should always be Phantom dancer, not IE. Keep the windwall / ult only when necessary, don't always use R when an enemy is knocked up by your Q, keep moving in lane to proc your shield.

I'm not an expert, but here are my advices

Take all the healing runes on him.
