Jumping to conclusions too quickly..
The game has been live for 10 days? There are always going to be some new players adding new Gil to the economy. Also, what about craft mats only obtainable via battle?
The sense that I get from the economy is that battle classes are Gil sinks; however, crafting classes have a number of ways to bring Gil into the economy. This would make crafters reliant on BC for mats, providing Gil for repairs which allows the crafters to convert mats into Gil.
It's simply too early to see if the balance is off. In a month, if everyone is still going broke then it will be time to adjust things.
