If anything, I feel this DLC would have worked better as a stand alone film (like Dawn of the Seeker.) I will not complain about the story as this DLC is loaded with new lore and plenty of explanations for a few unanswered questions from DA:I. It feels like both a goodbye to the current cast, and also a huge tease on what DA4 might be. BUT, it also manages to feel detached from the main game. Giving closure to the main game's storyline, and foreshadowing the next game in the series.
