Low invincibilty, that's all we need. I have a sneaking suspicion that it's a hitbox thing, like despite being airborne if u collide with a move whose hitbox is tall despite being a low u still get hit. Just make airborne moves low invincible it'll make every1 happy
Considering how often I've seen Hayabusa get swatted, like, 5 metres in the air, by a low sweep, I doubt it's a hitbox thing. It's a "lows can be anti-airs too!" thing.
