I think that a lot of the opposition is coming from players who rarely, if ever, engage in PvP in the first place.

PvP in FFXIV is very much a mixed bag, but I have done a lot of it because no match is ever the same. Something refreshing in an otherwise very predictable game.

There's a lot of ways in which open world PvP could become a thing in a way that didn't step on anybody's toes. For starters, it could be limited to a specific zone or server type. Secondly, it could be made with opting in and opting out in mind. That way it is entirely consensual.
