Titans are the front line fighters of Destiny. Toughest to kill in PvP (for armor stat) and great for the team in PvE because of their bubble shield. Titans don't need to be anything more. I completely disagree. It's like the analogy to a fantasy game. Hunters are rogues. Warlocks are Wizards. And Titans are the Fighters. All classes play their role well. Maybe when we get our third subclass you'll change your mind about Titans.
