Auction house - "Extra fee" when listing an item is WAY too high

When listing an item in the auction house, there is a flat rate "extra fee", depending on duration. This is an issue as it discourages the use of the AH for selling lower-value items, which would lead to a more active AH and also potentially be a way for new players to make money. The fee ranges from $50-$2400 depending on duration. Given that a stack of cobblestone costs $128 in /shop, this means that to make even a small profit, you have to list for a very short duration, which isn't very practical Not sure if this is actually a bug or would be seen more as a "balance issue", but given that RPG has the exact same "extra fee" despite having a MUCH different economy, for example a single cobblestone block is $35 there (baltop on there is in the billions if not trillions) I assume this was either copied from RPG, or simply a default value, either way it wasn't adjusted to fit this gamemode's economy. (already put this in suggestions, but want to make sure this isn't overlooked)
