You need to learn what opportunity cost means! You paid 60$ when you got it day one. You can know purchase this game for 25$. Ok let's say you purchase the dlcs now you pay 35$. That the purchase today cost then 70$. The game will devalue in two months. So let's say it cost 15$ for the game. You want TTK so you pay 40$ . You have know paid 55$. They are giving the outdated content of TDB and HoW for somewhere around 5$. They aren't discounting new content for players that don't have the game. Although your value is 135$. You paid the extra money for something called TIME!!! Not the game.
