Yasuo block with his wall lulus W

You guys can't whine about Yasuo if you misunderstand projectile with skillshot.

[zombie-brand-facepalm]

It's still a projectile just like old point and click stun gem. and besides, it's not a laser but moves fast like 1.

Skillshots are projectiles but not all projectiles are skillshots. Yasuo can block all projectiles. Lulu W is a very fast projectile.

it's a projectile so it can be blocked.
