Every class in the game is beast in their own way. I have all 3 and I have no favorite. I love my Hunter in crucible, blade dance a whole team while having the regen health per kill perk and invisibility, also love the Titan provide weapons of light when needed and shoulder charger the crap out of people in crucible and I love the warlock too, love the self resurrection it's dope for raid. Don't use it in crucible though I always go with Void Walker it's a bit deadlier to me if the whole team capping a zone and u got obsidian mind one. I don't think no one sucks or are bad. Just gotta know how to use each class in their own way.
