Need to address the Eureka in the room.

Which is fine.

I mean, that's what they're working towards with the coming "World Visit" stuff coming in ShB right?

As well as the changing of Datacentres and the like.

world visit just allows players to play on friends servers, megaservers place players with players from any server automatically. Maybe in the long run megaserver is thier plan, but we havent seen them say that yet.
