Dks are an interesting blend between DPS and Tanking such as that I can pull decent dps in my Tanking Spec (DPS Gear) a nice blend of Threat vs Survivability and the Rune/nic System is something that's completely new and very interesting.

I enjoy that as well, the DK trees have some analogy to the Feral Combat tree for Druids. These days you do have to spec one way or the other to be a really strong tank or dps, but you can have a spec for one, switch to the other role (even mid-fight) and still do half-way decently, particularly at later gear levels.
