I don't think its supposed to be Tank, Heal, DPS or whatever combination of fantasy tropes. Its supposed to be Wizard, Close Quarters Specialist, Long Range Specialist. But I still said "Yes, other reasons". Honestly, while Titans wear heavy armor, they shouldn't be "Tanks". They aren't going to be sitting there, aggroing bosses or mobs. They wear heavy armor to take more damage, to get in close and be aggressive. Its just a play style thing. Hunters are nimble, agile, whatever, and sneak around in their camouflage cloaks and stuff. They are supposed to be Bounty Hunters, Assassins, the like. They kill from a distance if possible. Again, just a play style thing. Warlocks are supposed to be spell wielders. While they still use guns and stuff, they have magical grenades, instead of conventional grenades, and things of that nature. They are supposed to be powerful but vulnerable, considering they get fairly close to their targets, but use light armor. While Voidwalkers seem closest to the Spellcaster trope, they really aren't much different currently. I think that the game is really missing out on what makes these classes, and even Races, unique. While all the classes behave differently, they don't lend themselves into their respective roles as much. Its really because of the DPS nature of the gameplay. There is so much emphasis on damage sponge enemies, and less emphasis on FPS style immersion. I think if Headshots were a thing, you would have a vastly different, more role-playing experience. Right now, there isn't enough incentive to not just use an AR as a Hunter, instead of a Scout Rifle, Sniper Rifle combo. Same with Warlocks and Titans. Why use a Shotgun as a Titan? In my opinion, Bungie needs to really do some updates to their mechanics to really deliver on the RPG elements. Right now, Destiny, both games, is a Bungie style shooter at heart, with some extra RPG elements and distinction. They just haven't taken the game to the next level, and made an immersive, role playing experience. I would have so much more respect for the game if Hunters really took on the Long Range Specialist role, etc. Right now, the gameplay is just too homogeneous. Its in the armor stats, in the weapon loadouts, in the way classes play the game itself. We aren't really offered different ways to play, because the game is fairly linear in its gameplay. For example, you can't run a strike more than 1 way.
