Thanks for the super helpful post. I wanted to join a server with other boxers and have been spending the day reading the forums. Seems the 4x DK 1x Holy Pally is fun and powerful.
It also appears that pve offers gear that is good enough for pve.

Wondering thought if the 4x frost DK would be capable of running 5 man dungeons with the pally healer? I would not want to have to have a separate team for dungeons. However if pve is not going to provide good gear, then I might as well go with pve focus.

Trouble starting over, but need to anyway. Is waiting to get DKs to open. Need to spend time building up some other chars.
