Lightbringer is a pretty decent server, I multibox only on proudmoore and kind of wish i branched out more before i leveled so many teams, the AH is very unstable and i have been having a really hard time unloading stuff as of late :\ if one of your main goals is mass farming and selling i would recommend a med-med/high pop server over one of the largest. I've been looking into leveling teams on lower pop servers to take advantage of AH stability.
