Yasuo thematical passive idea

First of pretty please dont kill me i neither main nor hate yasuo. This is just a thematical concept.

I always thought Yas passive never fit his theme. He's suppose to be a samurai, yet the crit and shield passive feel like more of a assassin/tank passive rather than a samurai. Plus its kinda unfair he gets 2 very strong passives while other champions barely have one. So i thought of a new passive to replace both of them.

NEW Passive:

##Open Wounds Yasuos critical strikes and damaging spells leave an open wound on the target, stacking up to X times. Upon exiting combat, Yasuo will sheath his sword, dealing Y damage per stack to the targets. Champions hit by Last Breath will immediately have their stacks consumed and take the corresponding damage.

This helps Yasuo feel more samurai-ish by giving him that Ruroni Kenshin vibe where he slices through them, sheath his sword and suddenly all the enemies fall down. Plus it gives more interaction with Yasuo. Enemies would want to keep Yasuo in combat to avoid getting hit by his passive. Using Last Breath to engage would mean Yasuo has to sacrifice the option of using it for a burst after stacking his passive on the target. Overall its mostly just to make him more samurai-ish.
