But no, after looking at it, I can see what you mean. Still, reading the descriptions of Healbot and Vuhdoo, they sound rather daunting to set up/use. I really am a newb, and not much of a computer wizard.
But I don't want to spend time not seeing the fire at my feet, even though I do have GTFO for this situations.
Reading a setup guide with Vuhdo helps a lot, and honestly most of the options you can kind of figure out as you go. I'd recommend trying it (or what ever addon you choose) out in something like a BG first. That way you can see your options in action without worrying about a raid group wiping if you're not completely on top of the healing.
