I think, at the least, they should allow you to drop weapons and armour if they aren't gonna put in a trading system. I personally would love it if they put in something like the GTS from Pokeman... like you put in one thing, ask for an other, and someone else can accept the trade, but make it balanced so that iif you put up an blue for trade, you can only ask for a blue or less(that way people arn't putting up the first autorifle asking for the Hard Light)
