Out of the 17 odd story mode missions and 5 strikes, why are the weekly heroic and nightfall strikers occasionally limited to DLC buyers. I am a loyal player and have logged countless hours. I also like to start my week off knocking the nightfall out for my bonus XP boost. Why punish us who refuse to buy the overpriced DLC. I am aware of marketing strategies, but this is unfair. I bought the game, why do I have to pay extra to play it.
