RAF and BG's

[Smoooth]

I kind of doubt RAF works in bg's. Rest does nothing since there is no real killing xp and the xp you do get isn't from questing which is the only other thing RAF affects. I could be wrong and this is only a guess.

edit: Actually rest does do something but its so small its almost nothing. NPC kill xp in av is like 55(55+55 rest -55 raid penalty). I remember getting 55 xp per kill in the 70s bracket so you can tell how miniscule it is.
