Titan obviously are not useless but compared to the strength of hunters or warlocks in the pvp, titans are weak. First of all, Titans have no ranged melee. Making them weaker in any brawl. Titans can only get a shield, if they Kill with their melee. But warlocks simply hit someone. Titans have no blink. Their shoulder charge can be countered easy by walking back wards, blinking/teleport or the strong range of pump guns. Their super is like a Panik button, good vs blade dancers. But that's all. No real range and can only used one after activating. Golden gun or a singer are even a threat to multiple faraway enemies that are not grouped. Titan grenades can't find targets like the arc bolt or the firebolt grenades.
