Thanks for reply, how do you plan on -5Shaman (for me I would have a 5th Shaman on my Paladin account for times when it is more efficient to grind with no tank);.
Can't see how shamans should be able to clear heroics, elements will be low lvl ( just lvv 68-70 skils) and should be dead on no time.

(I also liked either 3 mages or 3 warlocks with typically Priest but like to have at least 1 of each healer to try all) - 3 mages are okay, but 3 I have a doubts about 3 warlocks.
Warlocks dps is heavily dependent on procks utilization. And I have hard times seeing how any one can manage 4 accounts ( Pally + 3 warlocks) simultaneously. Tho 1 warlock is almost must have cause It will provide curse that will reduce Arcane, Fire, Frost, Nature, and Shadow resistances by 165 and increasing magic damage taken by 13%. Thus I'm willing to test - Paly + Rshaman + 2 Amage + Demo lock. Should be a good balance in terms of buffs and amount of procks which needs to be controlled.
