No, you don't. Only place Glanzfaust is obviously amazing is when you have 300% tp, and if you're saving 300% tp in Assault, Einherjar, Salvage, Nyzul Isle, ZNMs or any of the HNMs in the TOAU universe, your linkshell leader needs to punch you in the ovaries. Hell, you need to not even be there as monk on half those fights.
Glanz wins if you're about to zerg Bahamut or Kirin since you should be able to get 300% tp before those fights with no problem. And there's very little chance of the random in-game situations that can absolutely nerf the weapon occurring.
HOWEVER...
You'd have to be retarded to lose those fights in the first place.
