Bad news. I just logged into Classic to roll a character and I'm guessing they are only opening one type of realm at a time and letting it populate until it is full. There are only three realms in Americas - Blaumeaux (RPPVP), Barov (Normal, which I guess is non-PvP, non-RP), and Stalagg (PVP).- realm names have been declared, and there's only ONE PVE-RP realm -- Bloodsail Buccaneers. I'd suggest RPG.net members try to roll their characters there, in case a friendly guild is identified.
Oceanic has it even worse - only Swamp of Sorrows (Normal).
Given that I assume you can't cross-server instance in Classic, that's already going to make me playing this problematic.
