I remember back in 2.x that people actually (on my first server) camped out around the aetheryte in Mor Dhona and treated it as a market place to auction high end items as opposed to just selling it! It was pretty cool. They also did some gambling with the dice roll command. It probably wouldn't work as well these days with significantly more players, though. Back then, there was never a queue to log in. These days, there's always a queue.
