Windwall
Seeing a lot of posts about this ability. Why not just make windwall only work from one side (the side furthest from yasuo that usually faces the approaching projectile), wheres skillshots passing through the opposing side would remain unaffected. I feel like this was how the ability was envisioned.
Probably the only thing I find annoying about Yasuo is how he can dance around in his wall and become practically untargetable to any ranged champion from any angle. If we were to make him succeptible from one side it would give the laner and jungler opportunities to capitalise on bad positioning, bad engagements and just bad windwalls in general, creating some much needed counterplay. I remember thinking about how retarded the current windwall system was when i first played him on release. I thought it was a bug. Tbh it seems like a bit of laziness from the coding team.
