I selected yes. Reason being is I thought of borderlands and how trading didn't "break" that game. Then I realized borderlands had a story and the entire game wasn't about getting gear. Destiny on the other hand has some story but largely relies on people playing just to get that new gear that has just that much more light. Basically Destiny is all about the gear and if they added trading people wouldn't have to grind so hard and ultimately play less.
