No, they already spoke about this and they will not make a trade system because they would like each player to have their own "story" with how they got each piece of gear and each weapon. Which is smart. I used to want a trade system but I like to work for my rewards. If there is a trade system then someone who has multiple excess gallys could just practically give them out for a piece of crap weapon. It's a cool idea to be able to trade but at the same time it's not fair. It's RNG, just hope you get lucky
