I'm pretty sure Musketeer's first job is Corsair. Limsa is essentially a pirate town after all. I'm really hoping 2.2 is the patch that finally adds some diversity. New jobs for every class, or at least some of them. If this is indeed the Ishgard patch, that means we'll likely see the addition of a new Lancer job (Hoping for Templar - spear+shield tank)
