I used to do Dk and Prot Warrior Wrath - WoD. Now we are using DH Bear. I changed from Prot Warrior because they gutted the class and the Bear is there because the DK changed to Paladin healer. I really think this patch is better than it was, being a DH of Helya was a nightmare but we made it work. Tank comps should really only matter in Mythic.
