Errr....what? FFXI wasn't a PVP focused MMO. Like, at all. And the first time they added a PVP element it was a sports-style minigame called Ballista that DID take your character's home nation (i.e. faction) into account. In fact, I'm fairly sure only characters of certain nations could sign up for specific matches. I vividly remember repping the kingdom of San d'Oria on the battlefield way back when.
