Destiny is "story" driven game. There is no way around you missing out in content when they add dlc. Games like dc universe online and World of Warcraft does the same. You can have a debate whether or not if the dlc prices are fair but you can't expect to get more content for free. Theses are business and they need to make money. Maybe if cod ever makes a more story based/ rpg like game we can better compare it to games like destiny, the witcher or batman arkham knight in terms of dlc.
