I currently run a mixed team, and a pally + 4 shaman team. I leveled my tank first with the mixed team, and geared him that way so when it came time to do the shamans, I didnt bother with resto, as i needed more dps. Even on my mixed team my tank rarely takes damage, my priest just spams smite... 4 Gift of the Naaru works wonders so i try and pop it whenever i need it. Totems help, and i found that the brewmaiden works like a healing stream totem, so thats kinda nice.

I probably will spec one resto, but not sure which one....
