Consider, too, all of those scrubs that went "OOO ME MULTIBOX. IT EASY. LOZERS DO IT, SO CAN I!" and bought 4 more battle chests, then a week later goes "ah, crap. This isn't as easy as it looks. Screw this, going back to raiding solo." Those are basically freebies that bump Blizzard's bottom line. I can't see them nerfing it. It's just too much free money.
