I wouldn't mind a resto shammy.

Selfrez = wipe protection 1x per hour (untalented)
Totems can be either for the shammy or yourself (Windfury+Str+Healstream or WoA+ManaSpring+Str/Stoneskin/Tremor)
Earthshield is set-it-and-forget-it

The single target heals aren't as great as a pally, but there are some neat mana efficiency changes in 2.3 that could change that - plus WF is a beast. Take a totembot as well as healbot.
