Yasuo is somewhat balanced and OK to deal with until he gets one kill..
Then he snowballs all over your face and does 80% of your health in 0.5 second trades in which you have nothing to do back because hes already dashed away from you through 4 minions in that tiny amount of time. And if he has ignite up, then that "80% of your health" turns into you DYING IMMEDIATELY.
If he lands a knockup? Forget it. Doesnt matter if you're under tower. He gets a shield when he ults you. He has more CC than the average champ (AoE knockup, AoE stun, they last pretty damn long too). Goodbye life.
Oh. Youre gonna play safe? NO YOU ARENT. NOWHERE IS SAFE FROM YAS. STOP LYING.
does the trick
