I sincerely despise Yasuo. So much so, that I hope he gets gutted.
But, instead, here's my take on the make him more healthy.
Passive: Way of the Wanderer: Sheath: Every 4 seconds, after Yasuo attacks. If he has not attacked or used an ability, he will sheath his sword. While Sheathed, Yasuo's crit chance is doubled, and his next ability will have a bonus effect. Flow: Basically his shield from moving around.
Q: Steel Tempest: Yasuo slashes his sword in a crescent shape in front of him, dealing physical damage to all enemies hit. Additionally, Yasuo's Steel Tempest can block a single projectile if timed correctly.
Sheath Bonus: This ability can critically strike and is treated as a basic attack. Steel Tempest's cool down is reduced based on attack speed.
W: Wanderer's Flow: Passive: Yasuo gains movement speed based on his Flow.
Active: Yasuo slashes the air, creating a wall of wind that travels in a line. All enemies hit by the wall are knocked up and take a small amount of physical damage.
Sheath Bonus: Wind wall travels faster and can block projectiles.
E: Sweeping Blade: Yasuo dashes a fixed distance towards target enemy, dealing magic damage. The distance traveled scales with how much flow he has before casting. Max flow will cause him to dash 500 units. No flow will make him dash 100 units. Sweeping Blade consumes 25% of his flow on cast.
Sheath Bonus: Yasuo dashes twice as fast.
R: Last Breath: Yasuo dashes through a target champion, dealing a massive amount of damage and immediately sheathing his sword right after. If Yasuo kills an enemy with this ability, he is granted maximum Flow. If Yasuo's target is 300 units away from him, he will dash 300 units BEHIND his target.
Sheath Bonus: Yasuo inflicts true damage instead of physical damage.
