I’m not entirely sure what your point is here. I assume your point is that it would be redundant due to directional airdodges, but directional airdodges are too laggy to be used offensively, as you can with an airdash. Plus, having an air dash separate from the airdodge would give you even more aerial mobility. I guess this would be an issue if we were to get a GG character in NASB (or even Multiversus?), but not in Smash.
