I haven't seen a single video showing anything. Learned my lesson from the Dreadnaught reveal. I'm going in fresh. Not only that, but I already advised all my friends/clan-mates that I was setting my fireteam to closed and was going through all the story missions/strikes by myself the first time through, to take it all at my pace, take in the narrative, cutscenes and dialogue. After that, time to have fun with my clan. Let the grind begin.
