My question is if I had previously purchased the taken King legendary bundle that included Destiny, and all 3 expansions, could I use my original Destiny disc and still have the expansions attached when I started the game? I had sold my taken King edition disc, but I have a copy of the original Destiny. Does it matter what disc is used? I just don't want to have to buy the taken King legendary edition all over again if all the expansions can be re-downloaded onto the system. Any ideas would be helpful. Thank you.
