Tank Yas is trolll? Think Again
^^
His initiation is much better because he won't get completely one shot when he ults, and even without full AS or Crit, he is still very high damage. The only problem is that he is garbage early game, but when mid and late game hit, you can start initiating and racking up kills easily.
Note: I'm not playing ranked in this game due to the many problems Yasuo can have as a tank in certain matchups. I just wanted a game that I would just pick up and quickly play, no questions asked. I might play a ranked with him soon, so keep your eyes peeled.
