The only issue with Oceanic servers is the relative high latency xD. Our (Philippines') connection to the US servers is still better than our connection to SG/AU servers (because of fiber optic cables if i'm not mistaken). So if you want less lag, you may want to choose US servers instead.
Then again, because of the earlier Oceanic transfers, most of us have already transferred our characters to the Oceanic servers, and I don't know if we can transfer back to the already populated US severs in favor of better connection xD. (Hm.. I may try to post that as a suggestion, haha lets see..)
In the meantime, kitakits sa Dar'Nala haha ;D.
