Funnily enough DRK plays closer to a traditional Drk than ever before if the rumors are correct and it's DPS is highest. Sacrifice HP to deal damage. Really it just needs Blood wetting. Or rather it should have had it from the start and WAR should probably have never gotten it -- since draining has always been a Dark knight thing, not a Warrior type of deal. While warrior's should have probably have stayed more towards a light regen or HoC with a burst heal.

Other than that, I'd say a name change to Rune Fencer would be in order since they are still pushing the magic resist tank onto it.
