I mean which parts are you punished in. Other than raids which require a team (which makes sense), and crucible (which ya the match making is garbage), where are you punished for playing solo. Both games do the same thing for stuff like story missions, where you get more for playing with others. Nightfalls can be done solo (although I kind of wish they would make it so you could do normal strikes solo if you wanted, don't really see why not). Where in destiny are you punished for playing solo?
