I am not going to PVP much at all with this group. Most of the time I'd probably play them separately as like my main 5 box and my alt 5 box.

My decision is to go with this group:

Tanks: 2 paladins
DPS: 2 Ele shaman, Moonkin, Warlock, Mage, Hunter
Healers: Priest, Paladin

3 paladins for 3 sets of blessings and auras
2 shaman to cover all the good totems
Druid and mage are in my team already, mark and moonkin aura
Warlock for blood pact and soulstones
Hunter for aspects and ferocious inspirtation and someone to take all the agi gear
Priest for fort

All I need to level is 2 paladins and a warlock.

I actually made 4 new accounts already so I am going to go ahead and prepare this group. I will need a new computer before I can do this the way I want to, which might take a few months.
