I like to play my Warlock with the Voidwalker, because it makes it easy to clear out hoards of enemies with abilities that make enemies explode on eachother, a melee that can restore my health in a tight situation, and that awesome Nova Bomb. I play Defender for my titan, because it makes me more useful in team activities because I can generate a lot of orbs for my teamates, I can give them extra sheilds/weapon damage/damage reduction, and gives them a safe place to dance. I use Gunslinger for my Hunter, because being able to have increased reload speed and stability for every 3 precision kills is really useful. It also feels more useful for the raid because I can take out oricles really easy and free my teamates from bubbles in an instant, so they can get back to killing. What subclasses do you prefer for each class? You don't have to go into detail about why you play that class, but you can if you really want to.
