I don't think RAF was created for multiboxers per se'. Blizz is gearing up for WOTLK. RAF was created to get as many characters to endgame content as humanly possible. It just really suits multiboxers well.

If they did decide to give in to the QQ's, I believe there would be a huge outcry within their own ranks since there seems to be a number of Blizzard employees who multibox.

I was done with WoW back in 2006 and didn't play at all in 2007. I only came back because of multiboxing. Take it away and I'd be done with WoW for good.
