I started the game on Brynhildr (on the primal data centre), but the lag was becoming so much of an issue for me, I couldn't get t5 or ex primals content done without great difficulty (and much frustration from the groups I would join).

If you're Australian, or you're in the GMT +8 - +10 timezone, feel free to join us. Of the Japanese servers, Tonberry has the largest proportion of English speaking players. I wouldn't be put off by the fact that you run the risk of getting wholly Japanese groups in duty finder either. If you know the dungeon, its not an issue - and if you're new to a dungeon, you can always find an English speaking friend in an FC or a linkshell to help you out.

Warning: Tonberry is populated & restrictions apply at certain times. I had no issue transferring in the daytime (GMT+10).

If you come to Tonberry, feel free to send me a /tell in game.
