You were given almost everything you were promised. There's a difference between what people implied we'd get, and what Bungie promised us. One of the only things I can really think of things being "promised" (and I use quotes because they never actually promised anything, they just said things while the game was still Alpha) is that the game would be bigger. The only reason they cut out free roam space was because they said last gen wouldn't be able to handle it.
