As has been said many times on these forums....Forsaken is no longer sold as a standalone item. It is now only part of the complete collection bundle. The people who told you just the Annual Pass will get you everything you need either 1) didn’t know you didn’t already have Forsaken, or 2) have no clue as to what they’re talking about...as the Annual Pass has never included the actual Forsaken dlc. If you want Forsaken, then you need to buy the complete collection. You may even want to see if the game shop where you bought the Annual Pass from could give you a refund or store credit, since they advised you to buy an item you can’t use.
