Yup, everyone saw it coming. The 3.1 patch is putting some hurt on the DKs. This is sad for me because mine is finally tanking Heroics and could easily tank a raid. Their increased time on Howling Blast cool down and removal of damage caused by Pestilence will hurt me a little. I don't recall much else, but I think they're reducing our avoidance, too. Oh, and our Icy Veins or whatever no longer does as much damage reduction. Booooo.
Guess I will focus on my Paladin, now.
