TTK, special edition and all the cosmetic garbage are just a last effort to take as much money as they can from you before November when the hits start rolling out for next gens like fallout 4 and battlefront 3. If you don't buy it, then you will be locked out of daily and weekly activities. So if you want to play parts of the game you previously purchased, then you have to purchase more content. There are too many issues with this game to justify throwing money at the screen over and over again and I'm not waiting till year 10 for bungie to get it together and get ready for more of the same shit in destiny 2.
