These are the same players that believe the "team up, make new friends" hype. It's all about the bottom line, they just don't know it. The Investment Team knows that groups are easier to manipulate than individuals. Cosmetic items, emotes, sparrows and ships sell better if FOMO and peer-pressure can be used as a sales tool. Team play also keeps people playing after they would normally have lost interest. How many times have you seen people in the forums say "I would play more (raids,nightfalls,Gambit etc.) but none of my friends play anymore." The Investment Team's job is to manipulate us all but some people just don't see it.
