For the absolute easiest configuration, I would say Paladin + 4x Shaman

For a slightly less easy configuration, but overall more power & other abilities, I'm getting sold on Paladin, Priest & 3x Shaman.

My new team is a Protection Paladin, Discipline Priest, Restoration Shaman, and 2 Elemental Shaman. This gives me:

- Paladin aura (Resistance almost always)
- Blessing of Kings
- Power Word: Fortitude
- Power Word: Shield
- Power Word: Barrier
- CC for Undead
- Every totem buff
- 3x elementals
- Tons of passive healing
- Earth Shield

Even better, if you dual-spec your resto shaman and your proest, you can add another few thousand DPS to your team easily when handling content where you don't need a dedicated healer and aren't worried about the priest being able to throw out a heal from time to time.

So far it's still early going with my team, but it definitely feels like a solid combination. The upcoming buffs to priests (shield is 3x as strong, etc) seem like they'll just make things even better.
