Yasuo rework

I was thinking on the concept of a Yasuo rework and have come up with this:

Passive: Hitting enemies with abilites fills his resource bar, hitting champions fills it more. Upon reaching a full bar his next ability is empowered.

Empowered Abilities: Q- Steel Tempest: Yasuo performs an Iai (draw slash) causing Steel Tempest to hit in a sweeping AOE, damaging an enemy grants two stacks of gathering wind W- Yasuo also gets a shield of wind which is some percent of his AD and/ or his wind wall moves at such speed that it damages any enemies that pass through E- Yasou gains a short burst of speed and the enemy takes DOT as theyre enveloped in swirling winds R- upon activation enemies are pulled towards Yasuo by a tornado and when the ult strikes down all enemies nearby take damage from whirling winds
