Is it possible that a flag other than "fallspecial" could be used? By that I mean, is there any other element in the game that causes characters to be unable to jump, airdodge, or use attacks? I personally can't think of any but... yeah.
No, that's what I've been saying... In Melee there was an airdodge count (or perhaps it was boolean, I don't know), but in Brawl that's irrelevant so I assume it's taken out (even if it isn't, how the hell would we find it?)
Isn't Luigi the only one whose landfallspecial sucks? Is that really so bad? He has the best wavedash in the game, and spotwavedodge gives him any evasive options that he would otherwise lack.
The only remaining problem is ROB, and I'm confident that setting his jumps and fuel to 0 would be sufficient balance. Sure, he can attack, but I'd rather that than freeze the game.
EDIT: Ahahaha, I just contradicted myself. If we did that with ROB, he could just airdodge unto the heavens. Hmm, admittedly now I'm out of ideas about ROB.
I hate to say this, but we COULD restore his airdodge alone. It might make it kind of interesting, and is at least a decent immediate solution.
EDIT2: ChiboSempai, that's a great idea and someone should test that ASAP.
... I hate to be a noob, but does Jiggs still die when her shield breaks, or is that a SSB64 relic?
