Just finished the DLC, and I think they did achieve their stated goals of tying in better story with the large exploration zones. I never totally completed any of the exploration zones in vanilla DA:I. Past a certain point, I just stopped caring.
But this DLC was better designed than the earlier exploration zones, and finding things wasn't nearly as much of a chore. I actually completed the whole thing, and it never felt like a drag the way the Hinterlands did. I loved the Avvar and their lore, and the main zone story was interesting and touching, if not particularly complex. I do think the whole thing would've been helped by more cutscenes and dialogue. And I don't think I ever got any new companion banter either, though I've been hit with the banter bug.
If future exploration zones are like the Frostback Basin, I'm 100% down. Certainly a huge improvement over, say, Emprise du Lion or the Hissing Wastes. If this is how they're implementing exploration DLC, I'm curious to see how they'll do story DLC.
