Yeah, most of his moves are pretty laggy. I have friend who would just play Falco to mess around and I would occasionally see him go off-stage, D-Air and FF. It's something he would do in Melee and PM. He would then tell me how his moves are filled with lag and that it would've worked in Melee. It would be nice to see some buffs in his move-set, but I doubt that will ever happen.
