Bungie needs to implement a trading system between friends only. The reason they don't want a trading system is because people will start paying $ for online items between random people and Destiny will be ruled by those willing to spend the most $ on in game items. How would Bungie limit trading to just friends? Obviously Destiny players could friend random people and then trade with them. However if Bungie required you to spend a certain amount of time/do a certain amount of missions or strikes with your friends before you are allowed to trade with them you could regulate who you are allowed to trade with. Only the people that are considered your actual friends. 100 strikes and 20 hours of time in a fireteam with someone then you would be allowed to trade with them. Is this a good idea, or bad idea?
