The little glitches being patched don't bug me. The things they have changed the since melee that really bug me is just the overall freedom of movement and speed being restricted. I really don't see why they took out dash dancing... Having no kind of L-cancel makes it so you generally want to avoid fast falling so moves can auto cancel. Sure, wavedashing wasn't intended to be used the way it was, but at least every character could do it (yeah, it wasn't great for some characters but whatever) and it was just more movement options.
*shrug* I don't know, just my opinion, hopefully more movement techniques will be discovered as the game is released on the WII U in the US, but whatever.
