to get the RAF exp bonus you have to have 2 accounts linked and the chars have to be at the same level, or near to it for it to work. You'd need at least 3 accts, 2 RAF ones and a non raf with the 80. For a few dungeons the lowbies dont even need to move past the starting area, like shadowfang keep, SM Cath, etc. Quick way is to quest with RAF to lvl 10, use a lock to summon to SFK, and have an 80 clean house, then run out, reset, repeat until you are lvl 20-21. I did it and was getting a bit over one full level per clear and didnt take long at all. SM Cath is quick too, if you kill everything by the door of the cathedral the lowbies at the entrance still get exp. You can do that til lvl 40. it slows down a lot at that point, so you may want to just bot from there on. Plus, if you use master looter, you can gear up the lowbies with dungeon blues so when they start botting at 40 they have decent gear to work with.
