Do you need a new beginning? It's kind of tempting to go roll on a realm where nobody's been out of the noob zones yet, where the Dark Portal has yet to be traversed by players and everything is ripe for the conquering. But then again, it's also nice to be on a realm with a mature economy and people I know, so I will probably not be rushing out to Cairne myself. I know, however, that many of you have been clamoring for a new realm for some time -- go to it.
Update: Bornakk adds that there are no plans for new PvP realms, "as there are several low population PvP realms you can transfer or re-roll on right now."
