What would you replace Rescue with?

That would work too... but I was thinking something that lets the party member float back up off the platform when they do fall off, that way it doesn't make surecast or arm's length irrelevant, instead acting like a failsafe. If you didn't use your own knockback tool you lose up time, but at least you don't die.

Aah, I see. So it'd work for situations like Titan where the arena itself shrinks, or the final boss of a certain level 80 dungeon (which I won't name in order to spare any sprouts who aren't into Shadowbringers yet the potential spoiler) with the crumbling platforms. Or E3[N|S]. Basically, places where it isn't (necessarily) a knockback over the edge that kills you, but even just the disappearance of what you're standing on.

I like that. It still probably requires you to see that someone's about to fall prey to that and put Float on them before they're yeeted into the Space Where We Were Not Meant To Go, but that's not really any different than those moments when you actually manage to yoink someone back up onto the arena when they fall off the edge by hitting Rescue just before they fall.
