I got this game when it was released and purchased the season pass. the curse of osiris was horrible and a huge disappointment. warmind was better but still not much content. I feel that since you habe made the first 2 dlc free, the people who already purchased the overpriced dlc should get forsaken for free or refund us for the first season pass. With most other games when you buy the season pass it gives you access to ALL the dlc released for the game. but now crucible is unbearable without forsaken, but I already feel like I got scammed buying the season pass so I'm unsure about forsaken.
Sorry man, life don't work that way. Old content will always be discounted/given away when new content comes out as a way to get people up to speed. If you don't like the system wait until the yearly big DLC comes out and you'll get the previous DLCs for discounted or free.
