I apologise about that. Most people that argue against me when I talk about lore in the game's activities mostly use arguments like yours simply because they can't think of anything better. I'm tired of it, and you just came across as another one of those people. Sorry. Anyway, while your point is vaild, I didn't say that the Nightfall and/or the Strikes in general are there to spread lore. My point is that with the evidence the game has given us in Story Missions and Quests, it makes sense why Bungie chose not to bring the Y1 strikes to the Y2 Heroic and Nightfall playlists.
