Most definitely. If you feel that you have not received what you were entitled to, you should be. My point is that people feel that they are entitled to something that has not even been proven to exist, in terms of the DLC. Bungie says it is placeholder, and I believe them - because I do the same exact thing in my day to day development activities. It is considerably easier to ship assets if those assets are largely done - even if not functional. However, people were show video of what the developer build of Destiny had looked like - that is undisputed. But, you start changing the narrative, shifting the focus, and working on other aspects of the game - parts sit in a partially completed state. Sometimes that state is something that looks pretty close to finished - but it is rougher than you may think.
