The setup itself is here: http://www.dual-boxing.com/showthread.php?t=37658
I'm not saying that is the only approach to a Healer + 4x DK setup, but it is one that works/worked for me.

The video links don't seem to be working, but I've got a text version (in the post) of my methodology or interpretation of those videos.
So you essentially can read the setup, even if you cannot see/hear Mosg2 explain it.
