I don't think you should be able to farm gil directly, but rather items that can sell into gil. I understand w/ the current MW system atm selling items isn't the funnest thing to do still if we introduce gil to be easier to obtain through monsters then crafting classes would really lose their shine, who would farm the materials? why farm or craft anyways when there's gil readily simply by killing. Not to mention the inflation this would bring, like someone mentioned before, curor to gil chocoblinkers in xi atm.
