Me too, I've never in my life that I can remember, ever played a game, mmo or otherwise, that took content and features AWAY from the vanilla or previous dlc purchases of a game and lock them behind a paywall, or remove them entirely, when an expansion is released. Even the recent final fantasy 14 expansion removed no content from those that did not buy the expansion, aside from a few relatively minor things according to my roommates (again, according to my roommates, I have not looked into it myself) Hell the recently released dlc for elder scrolls online is the exact same story, those that did not buy it remain completely unaffected. They simply cannot access the new areas or use any dlc specific gear which doesn't matter because you can get gear outside of it that works just as well I am told.
