The thing CoE is clearly not understanding is that 3rd world countries pay hordes of people to farm gold for mere pennies an hour. Your average gamer is not going to be selling anything, because he has no chance to compete with gold farming companies who employ tens or hundreds of people.
Also, this promotes hacking by these Chinese companies, so they can just take your gold, and use your characters.
Really bad decision, but the game probably will not be popular enough to worry too much.
This company... I am proud to say I do not support. They are making BILLIONS and refuse to spend cash lest their shareholders revolt. Low budget indies make more updates than these money grubbers. But somehow consumers mindlessly support this.
