The way to do it would be to have a tiny cluster of English-flagged servers in the JP region, as a new and entirely separate 'datacenter'. Then give the existing players the opportunity to transfer off for free. I think a lot of Japanese players would appreciate it too. Those interested in using Japanese can remain in place while those who don't want to learn can play without the lag - which I still don't think is so bad it's unplayable even though I'm at 250-300 ping myself.

(I'm not against Oceanic players having their own servers at all, I think it's a great idea if there are enough people who want it. But complaining about the PF being mostly JP when you pick a datacenter that doesn't include the biggest EN community is weird. Of course it's mostly JP. It's unreasonable to expect every single server group to be majority English-speaking.)
