Ledge gimping sucks but its always fun and usually the players fault when they get gimped
i also hate it because the ledges still have that delay when you grab them from brawl, then when you get ledge Annoying Orangeed the person can just hit you on the stage anyway because you won't get ledge invincibility
you could try going back to stage, but that's dangerous and some characters probably don't have a good enough recovery to try it so really you're just screwed
also because there's auto-snapping you can't try to like... mix-up the opponent and actually go on the stage instead of for the ledge
