There is no "RP" server as designated by the game. The RP servers aren't official, just decided by players. So rather than say "Here are 4 rp servers, pick among them", you have everyone trying to crowd into one server and overflowing into another because that's the only place people think they can go to roleplay.
What happens to RPers like myself, who pick up the game to play and RP with friends, only to find out the server they're all on is always closed to me? What happens when I refresh servers from 3-6 am and Balmung never opens? What happens when I sit around at 5am to refresh servers after maint, only to find Balmung is already or still closed less than five minutes after the worlds go online? What happens when I can't even give Square money to let me onto the server I NEED to be on to play with everyone I know?
What do I do, RP by myself? Quit?
