I have been tanking a long time a dk both in man pugs and 5 man heroics.
However for the life of me I am having a very hard time deal with za more then zg itself on trash packs especially the mobs before the bear boss and some bosses in there.
My friend who is a druid healer can barely if not at time keep me up he is very critical so its hard to take what he says since he has not played a Dk tank at 80 or 85 but he healed his other dk friend much easier them me the other night so...
As such he and a few other have given me mix advice as to what I should be reforging and what runeforge I should be using to try to survive za better.
SO I ask if anyone has any advice on my character I would appreciate it, and I am aware my second profession isn't really meant for me or raiding (was a farmer alt a lot time ago) just more worried about my reforging and enchants and gems in hopes I might survive through za better and make zg a bit easier.
