Hardcore PvP players pursued Enchanting for the ring enchants, for example, while hardcore raiders leveled their Leatherworking for the Drums of Battle. In Wrath of the Lich King, the different professions get even more exclusive goodies designed to keep professions more or less in tune with their intended classes. Eliah reported about the passive buffs for gatherers, and they seem to be in thematically tuned to some classes. Take Master of Anatomy, for example, which seems to be a benefit given to Skinners. Traditionally, Rogues, Hunters, and Shamans were the classes who pursued Leatherworking and its complementary profession, Skinning. The passive benefit to critical strikes are certainly welcome to those classes, so players who chose to stick to their Skinning will actually receive a pleasant boost in Wrath.
