He already has 4 jumps. I left his glide this way because its exactly like that for Pit and adds to the whole air=good, ground=meh thing. Up B is getting changed, but it won't be controllable like that since that will either take up a lot of space or look stiff (as in no movement at all) and we don't want that, do we? His ground combat rating is outdated (i haven't updated them since 1.0 or even earlier) and so is aerial combat rating. Now its not as bad since knockback and damage on ground attacks were increased and aerial attacks are now slower or work differently (DAir and NAir are most obvious examples). Tail's range can't be decreased anymore without his tail getting warped badly. Model itself does not allows that. And even then, its not that much longer than Dedede (who technically has more range on attacks since he actually swings his hammer upward and downward instead of just sideways and thrusting it). As for weight, it is that low to balance out range, aerial mobility, recovering abilities, damage, knockback, etc., it also makes sense for anorexic flying creature to be light. And just to be more unique.
