Thanks for the reply however when I tested yesterday it seemed as if the low levels did not take a slice of the exp whent he 80 killed it, here is how im set up;
- Char1 recruited Char2 - both level 20
- Friends account - lvl 80 totally seperate account nothing to do with RAF
- All in one party with the lowbies sitting at entrance whilst the 80 goes off killing

I could be wrong but im pretty sure they lowbies didn't take any exp from the few mobs i killed :/
