Imo, the amount of gil generated is good enough.

In the last mmo, easily 1 billion coins were being injected in the market easily. That's still happening, and guess what happened? Everything is more expensive, some people have almost no coins, and others are like in-game versions of Bill Gates.

Atm, we get money though leves, and quest. That's more than enough. Why do we need to have 1 million coins if our buying power is going to be the same anyway. If you want to make money, go gather mats, or craft and sell.
