I heal with a holy priest, very easy IMO, u got a shield, an instant HoT, a ping pong auto heal, and big punchy group and single target heals. For easier fights, i just swap actionbars, and lolsmite, with holy fire thrown in there. I do 1k to 1400 dps in full holy spec/gear, which IMO aint too shabby. I also have her dual specced shadow, and she does double the dps, but it aint nothing compared to my shammy. I haven't boxed a resto sham, but it cant be too hard. I'm about ready to ditch a shadow off spec and go Disc, just to try something different.
