You should read the new section I added to the post. One thing you might be forgetting is that Destiny is actually going to have proper [i]sequels[/i], I.e. "Destiny 2." MMORPG "expansions" are their equivalent of sequels, which makes it more understandable that they make large overhauls to the game, but TTK [i]isn't[/i] that kind of "expansion," it's still a glorified DLC.
