Well I did a 3minute parse last night and did a consistent 700, but that was with sub-par str accs (mostly i136-142) and i180 weapon. I don't have the Hive Claymore yet. I had 820 strength. I have heard of another DRK on our server parsing in the 850 range with the Hive sword and i180 str accs.

But as Alphras sais, TP is a huge issue if a DRK is going into a raid with a PLD and is expected to DPS in off-tank stance. It's a good thing I agreed to do a 3min parse instead of the 5min one I wanted to do, because at the end of 3min I had 0 TP. Blood Weapon is a huge drain on TP and we have absolutely nothing to help gain it back. We can use magic to attack and regain our TP over time but that is a horrible DPS loss if your meant to be off-tanking and DPSing because the MP based GCD's are enmity based and don't have very high potencies.
