I remember Bungie specifically saying that they will not add a trading system because they want all the Guardians to "earn their guns" and I 110% agree. I know this is an exhausted topic, but hear me out: A. Can you imagine everybody in Crucible having the Vex Mythoclast, Gjallarhorn, Ice Breaker, etc.? B. From A to B, that means everything that we as Guardians receive will eventually become devalued and not as special to our Guardians. They may seem like they're "devalued" anyway because some Guardians have them already, but this game has and still needs to maintain the "separating factor" between those who earn their guns, armor, etc. and those who don't. C. Getting tons of Xbox messages in the Tower every time you go there from other players asking to trade, then if you don't answer or tell them no (politely), then they report you for fraudulent claims due to their selfishness and jealousy of not working for their guns, making us dedicated Destiny players look like idiots. D. Real money scams (aka paying for a gun someone doesn't have or dismantled after money transfer) to buy inanimate objects. E. Giving the right guns to the wrong people. It's not about the gun, it's about the gunner. F. If a trading system was implemented, buying guns/armor/items from any of the Tower factions is completely pointless. G. If everyone gets what they want via trading, less and less people will play the game and will not buy DLCs to upgrade their equipment. H. Fewer people will undertake the raids to get their gear/weapons/items, and frankly, they'll never have to do them if they get what they want via trading because of duplicate items given to a Guardian. If someone has the link to where Bungie stated that they'd never add a trading system, I highly appreciate it. There's probably more points, but these are just something to consider if a trading system were ever considered to be implemented into Destiny.
