First we must ask ourselves when all mmorpg games start separation pve from pvp like in GW2? In pve we have different skills in pvp other. FF should take example from game like aion imo. There is no true open world anyway, so SE should make for example 3 maps with open pvp, where we can fight each others, hunting, pk'ing others etc. If you dont like it you dont have to participate. No one is forcing you to go there...
