I think Trespasser is pretty good too. It’s not a Mass Effect Citadel send-off, but it ends the game tolerably well, and it wraps up the story of the Inquisitor in a really effective way, while answering a lot of questions about the lore and setting the scene for the future game.
I really enjoyed Jaws of Hakkon too. Well-made story with some really great background about the Last Inquisitor.
IMO, those two pieces of DLC are better than pretty much everything in the main game, other than the Grand Ball.
Didn’t much like Descent. Adds a bunch of lore that has fairly little connection with the rest of the Dragon Age mythos and ends the story with more questions than answers. Seems like a rule for Dragon Age that any content involving the Deep Roads has to suck.
