When I speak of RAF exp, I mean in the messages in the combat window where it specifically says (## bonus exp from Recruit-A-Friend). That is how I confirm the whether the grouping arrangement breaks the RAF bonus.

If there is no RAF exp nerf why is it a common thought to not link the lvl 80 booster in any way shape or form to the other (RAF'd) accounts? Is it a popular misconception? A precaution? (No, I'm not referring to this thread specifically, just speaking in general.)
