i think because the complexity when you are playing more than 1 characters at the same time, each class has its own game mechanism. In order to play multi boxing with joy, having knowledge/ideas of what you are doing is rather important. RAF imo , is a promotion that is also for exisiting gamers (who advanced in game or end of the road/bored, might as well be 70) invite other players (new comers, reroll, different classes), can progress in game much faster in light of upcoming expansion pack.

New comers who enlisted with RAF can do multiboxing, but due to very short time in characters leveling, this could cause a problem with GOLDS, in which you need to learn skills and get more suitable gears.

with all that i think we then assume those who is doing multibox + RAF might already have main 70
