Could we swap the Bid Amount and Buy Now (optional) to be default Buy Amount, while the Bid is optional?
I think most players prefer to just buy upfront on the AH anyway than Bid on it. So it might be better if we can list stuff on auction without needing to put a Bid Amount unless necessary. Personally I find the "You must enter a bid amount" just taxing. But that's just me, idk if others agree.
