They could have taken the content away even if there wasn't DLC, hell they take away crucible modes all the time. And add new ones. My favorite map was removed months ago. I can't claim it's a bad business practice for that can I? I payed for that map right? Wrong, Bungie can add or remove content as they like. You people don't complain when your given new content that you never paid for, but you complain when some is taken away.
