So I have a few friends who want to transfer from Balmung to another server, but the problem is they have a lot of gil and don't want to just give it up due to the gil transfer limit. I know this is an issue for a lot of people who would gladly transfer off big servers like balmung to less populated servers that have housing available but the biggest issue is the fact that they would lose a lot of gil in the process.

Would it be possible to have a vendor where we could purchase Allagan/Clear Demi pieces or some form of currency exchange so we don't lose the majority of the gil we have?

And if you're worried about it too much you could make the currency pieces cost more to purchase than they are to sell. Say for Tin pieces it could cost 50 gil to purchase with a 25 gil sell back rate. Bronze 150. Silver 600, Gold 2,750, Platinum 11k.

Unless someone can say otherwise; I don't see how this could be in any way game breaking or unfair.
