Taken king probably won't be the game busting expansion bungie wants you to believe its. It also won't be a total waste of cash as this is about the first time that destiny will have to sell on its own merits not just on preorder hype and Bungie's legacy. In short I would recommend waiting until release reading the reviews and deciding if it is worth your money. But don't preorder only idiots preorder, especially after the how debacle
