One can only hope. Unholy DK is one of those specs that is in fire need of someone to come in and fix the mess. For one maybe they can finally decide whether it's a Necromancer with a sword, or a really confused Arms Warrior that dabbles in Necromancy on the side.
Might be an unpopular opinion, but if there ever was a class that should make the transition from Melee to Ranged beyond Survival its definitely Unholy. That spec would barely need any changes to become a staff wielding Necromancer.
