Lol lets see if I can get all of these.
In a way this is a suggestion in that this server is losing buisness due to the economy being so haywire thus meaning implement a new way for the server to handle things
@Genesis
I understand that completely, but you have to consider the person B sells his card for 35 coupons great your helping lower the price, but as soon as that one price is gone you have the one person left selling his card for 65 and thus you have the impatient people who buy that card instantly thus keeping the price at 65 leaving the guy who sold his card for 35 sort of ripped off. So that sort of eliminates person A going out of buisness :\. Also we can't just break it down into that player B will hunt more cards because at this point Player A has most likely better gear and is able to hunt more efficently then player B which means player A has more supply coming in and able to start selling before player B meaning people might buy his product first
@The people who said this isn't a suggestion
As said before I don't know how other servers do it, but they seem to maintain a stable economy at least from what I remember and if I remember correctly everything in other servers was bought with zeny and donations didn't give you coupons, but gave you the item.
