Yasuo's windwall says it stops all projectiles. The definition of a projectile is a object moving by its own inertia affected only by the force of gravity. So by definition, yasuo's windwall shouldn't block tahm kench's q, gragas's q, ammo's q, blitzcrank's q, zyra's, evelynn's q, and you get the picture.
First off that's not even an accurate definition of a (real world) projectile. A ball rolling downhill is moving only by the force of gravity, but it isn't a projectile.
pro-jec-tile [pruh-jek-til, -tahyl]
And Riot defined it as such
A projectile is any entity with a velocity that is not classified as a unit (champions, minions, monsters, etc).
Haha I agree, I feel like it's blocks way more than just projectiles.
