Ok. So my brother and I were talking about this and wondered how long will destiny be truly fun? We already know reaching the level cap of 20 will not be too terribly difficult and replaying old areas once your a higher level is not nearly as fun. Borderlands solution was enemies level up alongside you but that isn't really possible in online game such as this. So when the story is done, you've reached the level cap, and crucible has lost it's charm, what then? DLC's maybe?
