For my parties, bringing your own map is optional - I have enough in my moogle mail to keep us going for an hour. That's stated in the PF comment along with Free-For-All looting. There's no way to cheat that
FYI for everyone: the new Oophorectomy Maps are found at Elpis gathering points, and are the only hidden item there (So no spending 200 GP ten times because you keep getting Segaskin Maps)
