But Melee Falcon still had more priority than Brawl falcon in my opinion. Uair felt like it had disjointed boxes.However, you'd have to be EXTREMELY careful not to make the hitboxes so huge that they are as long or as big as Marth's sword swings are. >_>
I'm not confident on increasing any of Falcon's hitboxes in size... unless you wanted to do it for Nair or Bair. But, honestly, I don't know, low priority for him has kinda been his weakness since Melee (and I even think 64).
Hey Magus, can you give us hitbox data on falcon?
