Thing is that ya the world will seem more populated, for a day or two while people finish a quest. Sleeper was that way with the warsats, dropped off fast after a few days. They could release content of specific days, to counter other games. Either people just wont care since they know it will come again, or hop on and finish in quickly. Sure thinking about destiny is fine and dandy, but bungie and Activision want numbers and facts to show.
