People need to learn how to ledge guard tethers in general.
I've been trying to figure this out. How do you do it with a character that doesn't have a projectile and multiple jumps?
For example, how are Marth, Ike, and Roy supposed to keep ZSS from tethering? It's extremely high risk, low reward.
I main Diddy and get some mileage out of z dropped naners, but when I play Marth I can't figure out how to stop the tether without putting myself in a bad position if they attack instead of tether.
I generally agree that people suck at ledge guarding in this game- I know, like, two people who edge guard my Diddy correctly (and man it hurts), and everyone else just moans and complains as they let me back onstage that my recovery is too good. But I'm struggling to figure out the tethers with the above characters.
