A number of changes were made for Death Knights. Several cooldowns were made spec-specific. Frost and Unholy's rotations remain unchanged for the most part. Blood received revisions to their Active Mitigation design to bring them up to par with changes to other Tanking wow gold specializations. Runic Power generation of Anti-Magic Shell was standardized, to make it more understandable and balanced.
