Like it was from the beta. Gold sellers benefit from selling money, not items. And you won’t see gold sellers hacking a dungeon to drop the arde dagger, then sell that for 20 or what ever.
Even if IMc wants to keep the trades behind a paywall make it so trading is unlimited between payed users and non paying users get like 5 trades a day, stacking up to 10 similar to what they did with TP.
