I was originally going to run with:

DKunholy tank, 2 boomkin, 1 resto druid and an arc mage.

After minor testing and theroycrafting this looks like a bad team to multibox as the 3 deeps toons are proc watch senstive/reactive. So im rethinking and looking for some class synergy feedback from those who box other toons

Current Main PVE team is:
(LVL 80's) Pally tank, 3 ele shaman and 1 resto sham.

Main PVP team is:
(lvl 80's) Frost mage, 2 demo locks, 2 destro locks.

So after a brief theroycraft im thinking:

(59)Dktank, (19) 2 shadow priests, (19)1 holy priest and an (32)arc/frost mage.

Extras: I dont like melee toons, range casters are easier to mbox, rotational dps is easier to maintain then proc dependant dps. Target the ground aoe isn't easily viable.

/thoughts?
