After toiling around with dual and tri-boxing, I made a mixed 5 box team. I am stil la relative wow newbie, but it isn't that tough. The worst parts are the class quests where you have to drag your entire team or go solo just to complete it. Only level 20 right now, and learning every phase of MBing at once. Gets frustrating but who ever said life was fun.

Also, I think Blizzard is trying to encourage multi-boxing. I think the RAF is directly tied to that. Draw an analogy to how the US has done business. Once you have moved out and gotten all the land you can possibly get, you then work your way building up on the land instead of wasting exponentionally more resources trying to acquire new land. They already have a bunch of addicts who shun real life to sit in front of a computer for hours/days/weeks never showering, or eating or getting laid. Why try to convert someone who actually has a life when you can just get MORE money from they guy you already have addicted?
