I posted about this situation on my server’s forum.
Honestly if the gold is an issue then just prohibit F2Ps from depositing or withdrawing gold from the bank since gold has little value to F2Ps what with the 1000 gold per toon limit and the ease with which this limit is reached. This is just another example of Blizzard using the stick instead of the carrot to try and get subs without realizing it’s not going to change things because there are those who F2P as a game challenge mode and they usually have one account as a F2P and one account subbed, and there are those who F2P because it’s literally the only way they can afford to participate in the franchise.
