Here is the problem with open world PvP. It is not very Final Fantasy. The main concept of Final Fantasy is to band together to fight off evil. Some games it works like WoW, but I think it would simply be immature to add it into a FF MMO. Besides, what determines if you can gank someone or not? It isn't like you are separated by different factions who are against each other. It saddens me sometimes that some people look at this as an MMO before a Final Fantasy.
