Teemo blind and gnarr
Can someone please explain to me how teemo's blind has the ability to stop mega gnarr's w(aoe slam). I understand it stopping auto attacks but, it just doesn't make sense, I can still toss a giant boulder and hit whoever I want with perfect accuracy but when I go to do an aoe stun it just stops mid animation if I'm blinded. Are there any other aoe abilities that it negates or was this just a mistake because in his regular form his w would be affected?
