Priority in the air doesn't really exist I thought. It's all range, I'm pretty sure any attack can trade hits with any other attack (as long as it isn't ground vs ground) given a certain timing and spacing.Yes, but he was arguing about priorities, and this shows that they have equal priority when Lucario doesn't abuse his spacing -_-
When I say that Luigi's aerial priority ***** Wario I mean the hitboxes around his attacks are just bigger than Wario's. 'Real"(grounded) priority doesn't come into play here.
