Doesn't this have more to do with what players are playing on any given week and how good they are and what spec they are playing....?
C'mon Blizz, there isn't enough buffs on DK. DK needs still more buffs, or another class will catch up DK's damage place on Overall and Boss dmg...Or, better buff WL and Mage with all their 3 specc. Only we want DK, Mage and WL as meta classes in WoW...
If Windwalker ever did good ST damage you know Blizz would grab the nerf bat and go to down.
Druids with by far the weakest tank spec, now brought to you by two DPS specs in the bottom third! "Do you guys not have heals offsets?"
