So any guilds on the Oceania servers yet? I'm returning to see if the lag is actually better with the new servers.

You may have noticed new US realms opened before the planned Oceanic realms, the reason for this is two fold. The Oceanic realms exist in specific geographic locations. This is done to provide the quickest information travel time from client to server, aka a lower latency. The hardware these US realms exist on is not in the desired geographic location for an Oceanic realm. The second reason being that it's important players looking for new realms, but that may not live in an Oceanic time-zone, be able to play on a new realm closer to their own time-zone, instead of playing on an Oceanic realm as a compromise. This can help ensure that the Oceanic realm population consists of players more or less existing within the same play schedules.
