My long term master plan is:

Port Pally / Resto Shaman / Mage / Boomkin Druid / Hunter

Group benefits would be:
3 that can heal
3 that can rez
2 that can tank
1 battle rez
Blessings
Intel Buff
Gift of the Wild
Ports
Mage table
Moonkin aura
AoE
No gear would go to waste

The hunter doesn't really add much to the group but I really enjoy having him. I could sub him out for an elemental shaman and get some good benefit out of that or maybe a priest for fort but I'm not real big on shadow priests; just a personal preference. I think Pally / Shaman / Mage / Druid / Priest would just about cover all the major buffs and group benefits.

Maybe I'll make a priest I can keep outside just to buff Fort on my group ha!
