We don't need a new thread for this. There are plenty of threads about tanking already, plus this is dangerously close to a WHAT IS/ARE THE BEST SPEC(S) post.
This is a quick question for the DK tanking community:
Are you planning on dual specing into a dps role - or are you going to effectively pick two tank trees (I am leaning towards a Deep Blood / Deep Unholy) so you can spec most appropriately for each encounter? My thoughts involve Deep Unholy for AOE / Magic mitigation - Deep Blood for EH and single target TPS.
What are your thoughts as to the best *two* tanking trees?
