The person who wrote those cards was hired 7 months before launch. The cards weren't a planned thing. They were only added in when they realized how much of joes original story had to be cut to make sense with there new more inclusive story. Those cards were a hack job to give you fan boys some ammunition to say "but the story is in the cards!". If it's not in the game, it doesn't count. You wouldn't say destiny has matchmaking just because there is a recruitment feature in the forums. So don't say destiny has a story just because it's in the cards.
