1. What is unholy DPS?
Unholy DPS is one of the biggest roller coasters you can step on as a death knight DPSer, in that almost every major patch has bought huge changes to the tree, sometimes making it totally overpowered, sometimes slamming it down into the dirt, sometimes making a basic unholy spec look like a convoluted Escherian nightmare. In Patch 3.3, it's leveled off into a solid, dominant powerhouse that combines stronger diseases and physical damage with the added bonuses of a cool pet and a very powerful magical debuff. It's essentially the choice for any death knight DPSer who wants to maximize their DPS.
