Wavedashing pointless? Ever heard of wavesmashing? It's when you wavedash then do a smash. With wavesmashing it's easier to hit multiple times with many down smashes. You have to use the c-stick. Do you even use the c-stick? It doesn't really take time to do one. Wavedashing is not mainly for transportation. There are many other uses. Wavesmashing is only one of many. You couldn't do a smash while running unless you jump cancel, but wavesmashing is way easier. Some characters wouldn't nearly as good without it. Go to someplace that has true experts and you'll see the uses. I'll list a few uses.

Wavesmash
Wavedash followed by grab
Wavedash to aerial attack
Transportation (for Luigi, Mewtwo, Samus, and a few others)
Wavedash to tilt
Mind Games

I'll post more when I get to, most likely with my HRC scores.
