Nerf the war or buff Drk/pld that is the question.
Actualy i think the war look like the finished tank. why Pld don't get only a force debuff and the dark only a intel debuff. why the pld don't have a mechanics to make him more interesting to play : the war have rage stacks, the dark have the dark arts.
Why the pld and dark get more punished than the war to swap stance.
and no war don't have 50% more dps than others tank if it's the case maybe your war is stacked with force and you not.
i think you should ask Buff, not the nerf.
