Of all the nonsense people have bitched about in this game, this is the one thing that isn't nonsense. This content was part of the base game people bought and shouldn't be removed from their grasp. Especially with how our light/power level is throttled to offer no additional benefit after a certain point, the only possible purpose of this is to try and coerce people to buy the DLC. It's a blatantly deceptive business practice. Even the strike quest step for the Legacy of Acrius got boosted up to 330! If it was base game content it should remain obtainable by people with the base game.
