A surprisingly simple solution.
As a part of the Realm Reborn initiative with Final Fantasy XIV, items and money are being reworked with astonishingly simple solutions. Gil, as it stands, is going under what they call Currency Redenomination, reducing costs, rewards, and held currency by 1/10th, or in other words, removing a zero from the end. This is not a rule, but instead an overall guideline.
Beyond that, there's a laundry list of changes to graphics, money, crystals, and items. When the game's combat gets overhauled, much of this will become important to know.
