Both Titan and Warlock can be barrels of fun. Punchbro and Void ho are carnage on an industrial scale. Punchbro and your preferred shotgun are a blast. And everyone should get to experience the Void ho/Obsidian Mind/Bad Juju orb machine once in ther Destiny life. If you are after efficient economic expansion, create more hunters. If you long to eat stars for breakfast and nightmares for brunch, create a warlock. If you you are troubled by the idea that there are too many Dregs that haven't been punched into there constituent atoms, or long to go at a Fallen Major with nothing but your fists, then create a Titan.
