I am curious because one of our priests does a ton of overheal. We just started raiding naxx as a guild (lots of our guildies have been pugging it), and the better geared of the two healing priests just respecced DPS so if he ends up coming as DPS on Friday then it'll be me and the overhealing priest. Meters aren't everything (or even that much) for healers, but he's always lower then I am, but top on overheal. I don't play a priest, or understand overheal, so I've no idea if this'll be a problem or not for us come Friday. It's only our 3rd run, but last week we cleared 3 wings and didn't wipe once on a boss till we got to Grobbulus (I think we don't have the DPS yet to get him down before he starts injecting us faster then we can lay down the clouds and get back to what we were doing.).
