Why don't you like me anymore?
Or are you talking about the hardcore band? My name is in reference to Dune, not the band...
But yeah, a lot of competitive players can't pivot. Wavedashing was a much easier solution than pivoting and had the same basic functionality (spacing), so few characters in Melee really benefited from pivoting, particularly because their wavedashes tended to be longer than their dashes. The main exception would be Marth, but still, most Marth players don't pivot.
The loss of wavedashing is still sad because I am a very technical player and a Fox main...I wouldn't be interested in playing Fox without all the stupid flashy shine turn arounds etc. That's why we play, right? I also second ICs, who are going to be trash without a wavedash. But I'll find a new main, or can go back to Captain Falcon.
