I agree that this would create an unfair advantage for Supporters. If there is a desire for changing options for everyone on how to list players, that's a different idea. I would actually like to see something on the player page, probably over the Warning message before the final button is pressed to list the player, a one-sentence addition that says "[Player Name] will be on the Transfer List with an initial Auction Ending on mm/dd at hh:mm:ss." Sure, somebody who knows exactly how long auctions take can do the math themselves, but not everyone knows this, and this extra sentence will be a big help for everyone in their final confirmation on whether or not to list the player. If it's not too hard to add, I'd like to see this.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
