The new GTN deposit is a completely negligible amount of credits, and is detrimental to the GTN economy.
As it stands, there is little to no punishment for canceling auctions and re-posting, rapidly undercutting the competition.
I believe this was changed in 1.5 to probably avoid players with credit caps smuggling credits via deposits and mail, but can it be looked at?
Should make items cheaper, which means F2P players can afford them, and makes it less likely that gold farmers will use the auction house to build credits, and will make auctions more competitive.
Don't think it will be changed.
