Long story short -- when they just put out the other day a new DLC package, they took away content people who bought the base game had access to and must now pay a fee (the DLC) to get it back. The Heroic and Nightly strikes are now only for DLC expansion pack owners, formerly for all. The snipe is worse as they're the two best ways to gather rare goods and and items including cryptarch engram rewards to get the better/best gear of the game to properly level your guardian to handle the actual game at the later levels offered. Now it's turned into a slog, much like a microtransaction tablet game where you can take months or days buying added gems to get the content.
I'm looking at likely now selling off Destiny as I find this repulsive. I shouldn't have parts of a game I paid full retail for snatched away if I don't pay them more money to re-enable it.
