I only use my hunter in pvp. I never use a shotgun and don't think I ever will. As far as supers go, hunters do have the edge in terms of duration but they are so easy to counter. If I pop blade dancer and run into a titan it won't matter how many hits I get in, if they smash me with their super I go down and they carry on. Same goes for the warlocks super. And grenades....warlocks have the edge on that one. I rarely get a kill with a trip mine, if you die from one then you probably didn't have full health/shield.
