I can only really speak for hunters: Gunslinger offers quick and steady movement and damage. Using golden gun with combustion and keyhole is insane. Chain of woe and gunslinger trance reward the accurate fantastically. Bladedancer is great in PvP and PvE, as is the gunslinger. PvP I use backstab and one shot people with my melee, quick draw for instant ads, hungering blade for devastating super. And PvE I use all the invis perks. In the abyss I run max agility, full invis, and I just stomp through, bring a striker with you and when the thrall get to many in numbers just fist of havoc them or hungering blade them. (This means no stalker which I don't use until crota.) And then there's the unbeatable exotics. Symbiote is one of the best in game, third man is the bladedancer equivalent, ahamkara spine is a little lacking but still alright, alpha lupi is better for a medic bladedancer but all around useful, we don't talk about ats, dance machines are fantastic for PvP and now that the glitch is fixed good for end game, knucklehead is also great for PvP. Not to mention the new Hunter ahamkara boots we have coming, gives you an extra jump on your double jump? My God, hunters will be sniping from the pillar on b in the shores of time! I can't wait. Other classes are great too, but hunters are for me. The entire essence of them is just exactly how I wish to play, whether it be gunplay or character/roleplay.
