As a Yasuo main with 700k exp in him I laughed at this. 90% of champions counter Yasuo so hard and are far worse, but you cry about Yasuo. As Yasuo, you have to work 3 times as hard as your point and click stun champions. If you get stunned as a Yasuo it's basically death. He literally picks his strength up 35 minutes into the game. There are no tenacity items for him to use. He can't spam his speed like Jax, Xin, or Trynd do. He is a close range fighter, but is super squishy. He can't go into team fights without a 70-80% chance of certain death.
It takes a long time to learn Yasuo for most players, the reason you get shat upon is because instead of relying on your point and click skilless champions, Yasuo players face shit until they get good. Every time i play any other champion, I shit upon people like you because unlike my Yasuo main, every other champion is super fucking easy to sit around and kill with.
So when you get shat upon, understand, you are bad for not being able to counter him considering 90% of champions have slows, stuns, and do far more burst damage.
You are bad because you have all of early game to rekt him.
You are bad because he does no damage until he has 3 or 4 items into the game. Whereas leblanc hits half of your hp with her kit, yasuo does 1/10th your hp.
You are bad because literally you can just bait out his windwall with no skill.
you are bad because his passive is easily shot down and the shield doesn't block anything like Malzahar's does.
You are bad because all you literally have to do is sidestep his tornado and he won't ever ult you.
I can go on and on, but you are blaming yasuo for your lack of skill. On top of that Yasuo is balanced. Cry about Jax being broken. Cry about Hecarim being broken. Cry about actually broken champions not champions you just don't have the skill to beat.
