We're having major issues with his DPS while progressing on Normal Siegecrafter. He simply can't kill the boss fast enough. Sadly due to a miscommunication we do not have logs for tonight, but here is his armory:

I'm not really looking for specific details of course, but any guidance on how to actually do DPS on these adds would be appreciated. He is dragging the adds through the missiles and saw blades, but it's just not enough. He's doing 70K dps and getting the add to about 30% when the next one spawns.
So, what should a Blood DK do to maximize damage?
