Since Y'all Always want Yasuo Perma Banned
I made a new kit idea with the same mechanics
Yasuo passive changes to bonus armor pen. he can still have that recharging shield Yasuo Q passive allows extra crit dmg 50% bonus Yasuo W readys and if a projectile comes his way he can reactivate and create a wall for 1.8 seconds. if you q with the w active it will deal bonus damage and remove the wall portion. Yasuo E now increases attack speed for more stacks Yasuo R when done cutting for a few seconds your crit chance is doubled
This should enable yasuo to be ruthless late game allowing him to build much more like an assassin. his base damage would be rather low so he cannot go tank. but his ability to duel and outplay 1v5 will be much higher.
