I wanted 5 DKs. I was going to put them into blood almost fully so they could basically heal themselves. But blood's healing got nerfed a little. Then it scared me, if I had 5 warriors (although with crazy less healing), I would probably not feel safe with instances near my level. Sure if I out leveled it, it might be okay, but with 00000 healing, that doesn't seem safe. I do it on my hunters, because I have 5 pets and even if 4 of them die, no biggie. But if even 1 DK dies, I am screwed. So I am going with my 60 shammy main, and put him on an alt position and run 4 DKs. Totems might help (anti-fear, healing, str/agi, windfury, etc). A wipe recovery (self-res), AOE healing, single healing and res. It just seems like the best way to do things. It will make me feel more relaxed and have fun instead of dreading any loss or mess up. I am also not scared of melee, my shammies are melee/resto.

I wish you luck and have fun.
