I am planning on 4 DKs and a tree/ or an 80 DK to tank/boost. Got two through the start and thru the Dark Portal. Will work more this week and then box them a little this weekend.
I will look at the builds as I have just picked what sounded good. 1 is blood and one is unholy. My 80 DK is Frost/2hd. The tree is 65 so will help keep them all going when the self-heals fail.
