Gold sinks need to be target at where the gold actually is to be effective. Blank gold sinks that are the same for everyone don’t work. They just make things more annoying for those that already have less. If they want to reduce the amount of gold in the game they need start taxing the AH gremlins. Any money that goes to them reduced by x% depending how much gold they have on their account, AH posting fees increased by y% depending on account gold etc. Once that gold is in proper circulation again, blanket gold sinks like increased transmog costs can work.
