Thanks guy....so I should use a booster account C then link A to D and C to E which will yield me 4 account that will get RAF xp.

Will a level 72 Mage be a good booster as I don't have any level 80 chars. I was causal 3 boxing until the computer died on me a few month ago. Now I take this opportunity of getting a new motherboard and CPU that can handle 5 boxing to play 5 chars at one time.
