Open world PvP is a bad idea in general. You are invariably going to get players who run around killing anyone that's a gatherer/crafter or lower level than they are. And when the inevitable, "What the hell, I was just gathering/crafting/chatting with friends/company mates here!" you will just as invariably get the defense, "lol i thot u were a bot"... There is no getting around it. "But you can just report these people." will do nothing as these players do not have a hive mind and shaming people on the forums can get you banned just as quickly. The notion of open world PvP also flies in the face of what makes a game a Final Fantasy game. We are heroes, one and all, and heroes don't kill indiscriminately. Yet this is the point of PvP, indiscriminate killing. The PvP we have is the best you will get.
