What Yasuo should have:

• movement like teh wind
• potent and disciplined abilities and strikes
• powerful but somewhat unwieldy attacks; the man is wielding a Monster Hunter Longsword, for crying out loud

What Yasuo should not have:

• literal actual dbz speed, aside from warping with his ult
• A Windwall that costs nothing, lasts 4 whole seconds AND stays put the entire time
• an AoE tornado that travels at mach 4 towards your soon-to-be corpse

Things that would be cool if Yasuo did have, making him more flavorful while also giving him any sense agency whatsoever:

• a Windwall that moved forward at a good pace, eventually no longer being in between Yasuo and his target (potentialy slows as well? Too much?)
• a longer ranged but slightly slower initial dash, at the cost of significantly shorter dashes tied to a cooldown for a time afterwards
• Any mechanics whatsoever tied to his wind meter (i.e. Windwall/additional dashes spend it)
• A Q that instead of being quick having a lower cooldown based on attack speed, is a little slower but becomes more powerful instead, like a really precise and disciplined jab with a giant sword would be

But alas: I am just venting as a Yasuo hater, not as a Yasuo main. He's titled The Unforgiven. He has it coming.
