I've come back to WoW and found an abandoned level 69 team ready to go. After a couple of years overseas, however, I really don't remember my play style or anything with them. There is a pally tank, 3 shamans and a druid. I plan to respec them all from scratch since even the 3 shamans have different specs. The druid has me wondering what to do for a healer.

I could do:

Pally (Prot) Tank
Shaman (Ele) DPS
Shaman (Ele) DPS
Shaman (Ele) DPS
Druid (Resto) Healer

or:

Pally (Prot) Tank
Shaman (Ele) DPS
Shaman (Ele) DPS
Shaman (Resto) Healer
Druid (Bal) Boomkin DPS

It seems to me that if I went with one of the shamans as a healer, I could also dual-spec the Druid to Feral for those times when I need an off-tank.

What's the community's thoughts on this?
