I hit 214 at the end of my last Titan EX run with my iLvl 90 BLM without the LB. It depends on the fight. More movement, lower DPS. From my experience, we're specialists. High burst and AoE damage, but because of the Astral/Umbral stacks and MP regen, we are not high on the sustained DPS list. My i90 DRG can stay north of 280 on Titan EX, for example.
