Yeah, I agree that a trading system would be an excellent idea to implement in Classic. It might take some work, but if it's set up like it was at Easter, like some of you mentioned, then I don't see the problem. Say that 2 people have hats they don't want, but each wants the other's hat, so they trade and get the hat they want in exchange for the one they didn't. Win-win. And of course there'll be some downsides to this, but I think the majority of Graalians would love a trading system.
One thing I don't like about Classic is when admins don't answer your PM. I mean, sure, they get a lot of PMs a day, but how hard is it to type up a 5-30 second response?
