I'd love to see a warlock multiboxer clearing heroics as easily as shaman do. If you ever get to that point, post some footage. I'd be ecstatic and switch my warlock group back to my main group. They seem to be buffing voidwalkers in the wotlk, but I doubt they'll scale enough for heroics. I'm mostly a pvper, but I'd still enjoy clearing heroic 5 mans as well.
