A few Yasuo's Windwall suggestions by a random group of friends

Note: Not all suggestions got to take effect at once. Also, I don't understand how formatting works.

Make Yasuo's windwall a skill shot ability: It is already a skill shot ability, but imagine Yasuo's Steel Tempest blocking projectiles or a few basic attacks (in a small area).

Make Yasuo's windwall's width based on his current health: Something like when Yasuo's below 30% health, bigger windwall. Otherwise, small.

Make Yasuo's windwall block just some of auto-attacks: Like, 33.333% of auto-attacks passes through.

Allow certain projectiles to pass Yasuo's windwall: Similar to how Riot Games changed invisibility to invisibility and camouflage. Nidalee's Javelin Toss (spear) can be blocked by the windwall but Blitzcrank's Rocket Grab (hook) can pass through.

If you have the power to change Yasuo's Windwall, what would you do (instead of deleting it)?
