It's 100% time for regional servers. Not ALL servers. 1 English ONLY server. If you don't play during english prime time, then don't transfer there. If your vagina bleeds to play with JP then don't transfer there.

This sub 400 online thing per server is a bit too low. I get that it's a JP game and the JP pop is still around 1000 but you could EASILY put most if not all NA players on one happy little server.
