I can't kill anyone else in PvP on my Marksman, even though I can slaughter plenty of mobs in AC at once. I think the Marksman needs more defenses for PvP reasons. The class balance is off, people play toons that are almost unkillable vs the Marksman.
And you really can't complain, you killed me no problem the other night on your lightbringer, while I couldn't damage you...
