Well, Hello I am new here I have been having problems tanking heroics lately and I did not have any problems in normal instances. I was wondering if its just DK's cant tank as well or if i messed up something in my spec or my gear just plain sucks for heroics..
Death knights can certainly tank heroics and raid content. Your gear however still needs a lot of work before you can successfully tank heroics. Many of the items you are wearing are itemised for DPS. not tanking.
