The story that Destiny launched with last September was completely different from what it was a year prior. This is because the higher ups at Bungie weren’t happy with the original story that Joe Staten and Bungie’s writing team had been working on for years, and decided to completely overhaul the story at the last moment. Obviously if want to overhaul such a massive story with just a year to go before the game launches, there’s going to be some problems, which is why Destiny had such a massively disappointing story when it launched, and still does in a lot of ways.
