Lol, WD is needed if you're a good fox.
When did I say anything about wavedashing, and no its really not. Wavedashing is the most misconstrued aspect of SSBM. You can be equally good without it, exception being the floaters.
whoops, I read waveshining as wavedashing haha. and yeah, wavedashing isn't all that needed but in general the shine is still extremely helpful when fighting characters that don't get knocked onto the ground after being shined, and aside from that its a easy kill when off the stage haha. my bad =]
