If you look at the leader boards Titans are sorely lacking in the top 100. It is a sad state of affairs. Hunters are grossly OP when it comes to pvp with arc blade, invis, and other b.s. Warlocks fair well overall. Titan is built around armor and taking more damage which has been normalized in pvp. I believe Titans has slightly more armor due to class abilities but you still die to every one shot like everyone else. So the class design around defense is broken in pvp. It is not you. It is the class. It needs to be fixed but I honestly have no idea how. If you don't believe me check out the leader boards. It is hard to argue with hard data. And no.... good players do not only choose to be Hunters. Morons.
