Hunters have a health regen melee. They can also turn invisible. They do have an instant kill with golden gun. Titans and warlocks will use there special even on one person. At least hunters have potential of killing more than one. Blade dancers can be good. But I find myself getting killed by anything with a pulse in one shot. Specially a warlock melee. All in all I think hunters are well fitted for the PvP experience. I'm thinking you don't play enough to notice the greatness. That's not saying titans or warlocks are bad either but if I have a choice for PvP in going with the Hunter. I have been using my titan here lately and I do find it funny to special one guy or a whole team . I don't like using my special and getting gunned down by one guy though. Specially with the buff that make you more invincible. Makes no sense. Anyways.....
