Haven't finished leveling my hunter, but I feel they kinda fall short of the other two classes in PvE (Hunter is by far the strongest PvP contender, IMO). The major problem is that for Titan and Warlock, both subclasses are completely fine for PvE, as they all have useful abilities. Defenders can provide instant cover in sticky situations, Strikers and Voidwalkers can deal some serious AoE damage, and Sunsinger can either provide a buff to the entire fireteam or act as a failsafe against wiping out. My problem with hunter comes from the fact that only one subclass is really good for PvE content. Gunslinger is great for taking out oracles, and providing single-target damage. Bladedancers super feels kinda lackluster to me - all it seems to be good for is clearing out trash mobs, something that can be done instantly with nova bomb, fist of havoc, or hell, a well placed grenade. But anyway, that's just my two cents. Take it how you will.
