I follow a very simple rule.

Is it a multiplayer game? If yes, no mods of any kind. Play as the devs intend or don't play at all.

Is it a single player game? If yes, mods are acceptable so long as there isn't any kind of leader board and you have already finished the game by playing it without then.

This game, FF14, is a multiplayer game by definition. Therefore, no altering of the game should take place in any way shape or form unless it's already a dev added feature.
