Though one does not add in a feature into the game and neglect it. You might as well not have put that feature in the first place. Now you have to appeal to an additional audience who really do enjoy that aspect of the game. XIV is PVE focused, yes, but that does not mean it cannot encompass other features and expand upon it. Otherwise there wouldn't be things such as Gold Saucer, TT, PVP, etc. And you really can't say that there isn't actually a interest for the PVP side of things. Otherwise these 72 man battles wouldn't exist. Mind you, this is based on GC limitations and not player limitations.
