This.

If someone is truly interested in playing with their friends then there should be little issue helping them through older content. Not only is there an option to scale down to complete it normally there's the opportunity to do so at a much higher level and item level than originally intended, making it a rather quick affair to take a friend through a particular dungeon or trial pre-50.
