Why i think yasou needs a nerf

Every game in diamond i am with or against a yasou normal's or ranked hes there, this is becoming cancer, please read first then downvote.

I want this champion to be nerfed, gutted but i want is not what you guys deserve . From all the time and effort the yasou mains have put into this game. What i need, what the game needs is this champion to be nerfed one way or another particularly his wind wall. Lets look at the rundown.

His Q: I think this is fine in a good position.

His W: This needs a significant changes imo, i saw a post before of windwall consuming his focus and or can only use windwall with only focus up. I feel this is a great change in order to reduce his melee to range power.

His E: dash, dash, dash, dash all i see is dashes, i feel this needs a higher cool down when you can dash infinite dashes through a minion wave to get away coupled with movement speed items with w and e these changes could keep yasou in check with out reducing his main damage or power.

His R: Good ult good position no changes here for sure.

Passive: Would like to hear you guys of what you think of his passive.
