The main issue is that there is no trade system. The reason that Arenanet has given is to avoid scams, however to sell anything to the trading post (if anyone wants to even buy it) you do get ripped off. With the 5% listing fee and 10% retrieve fee, it’s ridiculous. Another thing is that people will start turning to mailing to trade, which will result in even more scamming that a secure trading system ever could. All I can say is that Arenanet’s alleged “scam-proof” method is a failure, and I do hope to see it changed in the future.
