The way I see it, Hunters are just good overall and slightly better than other classes, although right behind the hunters is the titan just because of the bubble. But the new subclass pushes the hunter enough to make them one of the best if not the best. The new titan Subclass seems just best in PvP because I just don't see much potential in it for PvE. The Warlock is torn in terms of where it will be best but I would have to say PvP right now until I get to play it.
