I having been playing my healer lately (5 shamans). I have ISBoxer and VuDo setup to heal with click area broadcasts. I have VuDo (Basically healbot) setup on all my guys so when I click on my main guy, it heals my other guys as well (it passes the clicks).

I know Eeny plays his healer also. He uses a druid, I use a shaman healer. I'm only about 1650, and I doubt I'll get much higher without a good dedicated healer.
