I tried a test usingmy 50 rogue and a level 1 mage on my RAF account and was only getting 1exp per kill and they were grouped. I understand I can tag it with the RAF accounts and then kill it with the DK, but I thought u could group all 5 together and use the 3x exp mutipler.
Since you mentioned dragging a low level 1 around and killing stuff with your 50 rogue...

...they long since removed the ability to do that using RAF. People were exploiting the RAF bonus by dragging around a level 1 ghost on /follow and getting full RAF bonus XP. This is not intended.

As stated in the official RAF faq, dated 8/8/2008...
�While in a party together, any experience gains are increased significantly.
�If both players are present when the mob is killed both players should receive triple experience.
If the mob is trivial to either character, no experience bonus is earned.
This means that if you have Player A (level 50 veteran character) grouped with Player B (level 30 RaF character) and they kill a mob that is level 32, since the mob is trivial to Player A, no bonus experience is awarded.

�If both players are present, experience gained from quests that are not trivial (gray difficulty or 5 levels below your level) will be tripled for both characters
