Gotta be careful with BOA's and RAF though, as you can quickly outpace your RAF partner and exit the range where 3x works. My wife had that problem when doing RAF with her brother recently.
How exactly can two people have BoA with Recruit a Friend? Doesn't RAF require you to have a fresh new account to bring a friend up with? The only way he could do it is if he hit honored with the guild and even then, you need serious gold to buy the three BoA items (assuming your guild has them). -- A government big enough to give you everything you want, is strong enough to take everything you have. -MLK
