Hello!I think that the economy and the whole community would take benefits from that. It would help solve various problems:
1)I often heard people complaining about the money required to get the novus with decent stats . Not everyone are into gathering/craft (and if they were no one would gain anything from that). So if you want to avoid gil-buying you have at least to give them an "hope" to get a huge amount of money quickly and fairly.

2)There are a lot of players that would love to do old fights but cant find a party because no one do them anymore. In this way there would be a reason to do them, not just to unlock requirements and in this way they wouldnt be totally wasted as they are now. Probably people would go farming them to split the money from the eventual drop.

3)People who are into craft would have an objective. I used to craft a lot, but now I dont feel motivated because I cant buy anything usefull or cool or that I cant craft by my self.
