Very cool. The questing-while-in-raid thing on WoD is a godsend for those of us that 10+ box, but this is a nice way for others to get in on the fun. My biggest concern with doing it with others would be how to coordinate all the schedules and staying together the whole time.

Did the group of 40 stay on the same quests all the way through or were they dispersed across lots of zones and basically just provided a way for others to level on a low pop PvE server?
