Wouldn't it be an amazing idea for events like Raids, Strikes, Queen's Wrath, and Public Events to directly influence the story of the next games and DLCs. If no one defeated Crota, then we would have to face his legions on new Earth missions. If we did not aid the Queen during her visit to the Tower, then she would turn her back on the Tower (not like she already does though...). Just as Defiance's TV show episodes influenced the MMO, so to should our episodes of experience influence the outcome of the war against the Darkness.
