This has been discussed time and time again. Trading is the stupidest idea anyone ever had. It will ruin this game, it's already been proven by how many people cheese the raids that cheating/exploiting is common practice and providing the ability to trade things provides the ability to dupe things. Adding any form of trading at all will turn this into borderlands where everyone is trading or just flat out giving duped weaponry away and it's a bad idea. stop asking for trading and play the game more.
