The issue with the servers is this, Square is expecting both NA and Eu to share servers, instead of giving both they're own. This is a HUGE problem, as both of these regions, are MUCH larger then japan is, so forcing them to share worlds, and an instance server, is causing servers to lock, prevent character creation, and causing the current issue everyone is having in game right now.

NA and EU need their own servers, both for worlds and instances.
