No, the user BEHIND the gravity hammer tends to be slow. Mind you, that's in game only, as, once again, a Chieftan was able to smash a Spartan-II in the faceplate in the lore, despite the latter being extremely fast.

Not to mention, this "juice" could also be a game only balance limitation, as the Fist of Rukt has been passed down from one generation, yet, it's able to be used over and over, despite having no different qualities to it than aesthetics.
