Hunters are extremely helpful with a ranged super if you kill the bosses instead of pushing them off. During time's vengeance when everyone has unlimited supers, a hunter with golden gun can take down a serious chunk of Atheon's health. The hunter grenades are just as helpful too, especially the trip mine grenade if used outside the spawn caves of the enemies. The only time the grenades are less useful is if you're trying to push the templar back instead of taking his shield down, or trying to guide Atheon toward the edge.
