not sure on AoH hitbox, i'd assume it's something like an inverted J depending on the side it's used, and also an inverted r in the air.
l like playing the not-as-played characters. they tend to be the most fun.
not alot of characters particularly love the air. haz is actually one of them. tao, valk, relius, bang, they have gameplans involving lots of air I suppose. jin fares decently in the air, so does hakumen. carl rounds up the bunch.
