Anyone try a 4x pally + Resto Shaman group?

I've been thinking about starting a melee heavy group sometime and thought that a prot pally + 3x ret pallys and resto shaman could be a strong melee heavy group. Resto shaman could provide the totem buffs and spam chain heal on the tank for aoe healing in aoe intensive fights. Has anyone tried this group combo in heroics yet or have any thoughts on how well it can perform in heroics?

I think you might find more success as:

Prot Pally
3x Ret Pally
Elemental Shaman

That way, you still have 4 DPS for faster clearing, and can rely on the 3xRets to provide most of the healing needed for most encounters. The chain heal of an Elemental Shaman is still pretty decent if you have to top off people for most AoE encounters. Run WF, Healing Stream, Str/Agi, ToW (or Magma) and just have the Shaman pew pew for most encounters.

Dual Spec him, but I bet you wouldn't need to pull him into full Resto that much...

Thanks for the ideas and feedback. I already have well-geared lvl 80 pally tank and a dual spec resto/elem shaman so that should make things much easier when I get my ret pallies leveled.
