Having a dedicated oceanic / English server would not create more opportunities, the PF would still be attached to the current worlds and be predominantly Japanese. The only area 'JP only' really occurs is savage content or learning parties, which isn't a great loss because you'll probably want other English speaking party members.

However; there really should be at least 1 server listed as Oceanic. A new player shouldn't have to research servers before creating a character, it should be simple and welcoming.
