I've been reading up on the economy of the game, and I'm sorry if this point has been made already. It seems to me that a big problem in the economy is that your gil gain relies too much on other players. I don't buy things from other people because I don't know if my stuff will sell and I can't chance losing the money. I imagine others feel the same way. If I had a steady daily income I'd probably worry less and buy more. My idea would be to give players a couple of gold coins for daily quest instead of crystals and myth tomes. Just a thought.
