It's plausible but I've always seen titans as a up close and personal type of class. Plus most supers don't do significant damage to bosses. Golden gun does maybe 1.2k damage for me on bosses and that's not a huge amount. Does it help? Sure. But I would much rather have a super that helps the team and not just damages the bosses. Like bladedancers super. In strikes, it's essentially useless because everything can two shot you with their melee. I actually use bladedancer as a support. When my teammates are down I pop it and go invisible to revive them. Even if titans had a ranged super, it wouldn't be that much more helpful. Quite frankly, I think defender titan would be more beneficial than a ranged titan.
