multi grab is mainly useless. in my level that has it, you have a reset pipe, and two p switches. then you have all the way at the other end a rope up top with a springboard on it, then another rope above it with a door on it. you have to keep using the reset pipe and keep grabbing more p switches until u can de-spawn the springboard. but that is really the only way it could be used, a requirement of multiple p switches through a pipe.
I disagree, seeing as multigrabbing can be used with a mean time limit or sections where you cannot go back. Nope, it has its uses, but mainly in TAS'es and Pit-hacks.
Of course you should fight fire with fire, you should fight everything with fire.
Oooh look at my userbar!
