Instances are cross server, so say someone flags JE and gets partied with Japanese players. Are you (or rather, could you be) now playing in an instance in the Japanese data center? Can you only be grouped with your own data center, but any server in the region?
J/W how that works. Got a full Japanese party for Haukke(sp?) Manor and I was trying to notice any latency differences.
Bring back random question thread, this topic feels dirty.
