They had an actual application process in FFXI because a real live GM officiated the ceremony and there were lines you need to remember/macro do do them. My wife insisted we do it back in the day and was pretty fun. Now though it's just a get your rings/etc and do your own thing kind of situation. They could just set up a few instances of different locales and have sort of a cutscene type thing with your characters that everyone gets to view if they want to speed up the process.
But if official SE employees will be officiating again then an application process will be necessary![]()
