Just a thought. Your damage has to cut through whatever resistances your foes have first. Dungeon foes generally have about 18000 resistance whereas non dungeon foes usually have about 9000. Penetration is what cuts through foe resistances. How much penetration do you have, and are you able to buff that with major breach? When fighting a dungeon foe, my characters usually do with with about 18K penetration (including major breach).
