But you forget that when the Death Knight class was introduced, it's not the fact that it had a DPS tree that kept the ratio of DD to Tanks the same. Two of the three trees were used for tanking, and the DK was completely overpowered in regards to tanking. Blizzard handed players a ready-made, high-level, ready to tank class to anybody that bothered ... and who were vast majority of players that rerolled as DK tanks? Warrior tanks switching for greener pastures. Who were the next most type of players to pick up DK tanks? People that wanted a fast queue as a tank and usually couldn't hack it and later turned to the DPS tree.
