I'm surprised Yasuo doesn't have an iai mechanic.
Like, remove the double crit chance from his passive and rework Sweeping Blade a bit.

E: Sweeping Blade
Range: 475
Static Cooldown: 0.5 / 0.4 / 0.3 / 0.2 / 0.1
On-Target Cooldown: 10 - 3.66 based on Critical Chance [10 x 0.99 ^ Critical Chance]
Active: Yasuo dashes a fixed distance toward an enemy over 0.55 seconds (based on his current Movement Speed), dealing Magic Damage. Yasuo cannot dash to the same target more than once every few seconds.
Magic Damage: 60 / 70 / 80 / 90 / 100 (+ 20% Bonus AD) (+ 60% AP)
After dashing through an enemy, Yasuo's next basic attack or Steel Tempest against them within 1.5 seconds will critically strike for modified damage.
Modified Critical Damage: 130 / 145 / 160 / 175 / 190%

Might have to adjust the numbers, I just guesstimated.
