I run a DK, Preist, 3 Shamans.

Right now the DK is 540 defense, 40khp, typical tank.
Preist is holy/disc he is all mp5/spell power.
Shamans are elemental they are all hit to cap, then spell power, then haste.

I just copied your specs for my shamans and my priest/DK just needed a little tweaking.

I got them all new glypths etc.

I am farming the deadly stuff but was unsure what to do for the accesories. I figured just typical dps accessories for shaman, mp5/spell power for preist, and the usual str, sta etc etc for the DK.

Does defense count at all in PVP?
