I dont know if you noticed aswell, but I also had extreme highs with both a Warlock and a Hunter, in my defence the teams I played against were very bad. But anyway, I take it you like looking at stats. But Titans can be very effective in crucible if and when used properly. I have seen teams of Titans destroy the opposite team, yet I have also seen teams of Titans get destroyed by tee opposing team. In the end, it really depends on your dominant playstyle.
