dash dancing is good but only neccesary when you play skilled opponents. Since its a mind game its all about tricking your opponent. Dash dancing, in combination with empty short hops, wavelands, and wavedashing can give you that much of an edge for your opponent to slip up. As in he tries to attack you and you aren't where he expected you to be.
Wavedashing is one of the few techniques I haven't bothered to master yet. Maining captain Falcon I have plenty of other aspects of his game to work on. Falcon's wave dash actually is quite impressive, watching vids of pros, but his dash dance is freakin insane.
You take the character tied with the fastest run(tied with fox), and the fastest dash(the extra burst of speed he gets when begining his run) and you have one crazy Dash dance.
