Is this really a question? Titans don't have blink, no ranged melee, shoulder charge cannot be used unless planned in advance, grenades are difficult to use (half the time when you put a lightning grenade on a wall it puts straight at the ground), no overshield for melee (unless you kill someone, wtf is that good for, the guy is already dead), and here is the big one that everyone forgets about: Titans are always stuck with a ton of armor, which has absolutely zero effect in PVP. So, while other classes can max out agility or regen, Titans are stuck with significantly lower stats. The only thing that will balance Titans with the other classes is if they actually account for armor in PvP, which I don't understand why they haven't already.
