I already commented this in response to a post. "I think it would be a bad idea. It would have the effect Borderlands trading had. You'd get powerful green (and higher) weapons through trading and effectively lose the excitement of a nice loot drop from a boss because.... The weapon in your hand is already better than than nice sexy new weapon that just dropped from the boss you just spent a half hour fighting. I think it would severely diminish the overall experience **cough**borderlands**cough**"
