I don't know how or what would be the trading mechanic but from a social point of view i support trading. It's human behavior since the dawn of time! It's in us. We need to trade, exchange, sell, buy. I don't know what would be the best way to add this feature but in fact, in reality..it need to be done. This is supposed to be a social game... Of course there will always be others who think that it's a totally bad idea. But you know there is a flaw when you got a certain piece of equipment that you don't need and your best friend beside you got a piece of gear that he can't use but you could and yet you are both stuck with it. It's like in real life trading...you know that someone at one point will cheat or steal. But you can't remove the trading system in real life because of a few cheaters. What you have to do is limit the damage. But for now, not having a trade system on the long run is pure damage. It limit normal human desire and behavior. Peace!
