Both."JP" as in Japanese-speaking, or as in "closest server"? I can speak both, but will physically be in Japan for the foreseeable future.
The existing servers are being split and half moved out to Montreal for latency reasons; thus labeled JP, and (NA/EU), really though you'll still see English players on the JP servers and vica-versa. The game also features a text/string translation system so it's no big deal.
Sorry guys I got mixed up.
JGAF and those who are joining us on Durandal Server (LEGACY) at launch: We'll be on RAMUH this weekend. I could have swore he said Mandragora but hey, now we know for sure!
Sorry for the confusion. Pass it around to the other's if they don't check this as often, ta.
