Yeah, the game suffers greatly from a lack of any kind of epilogue or CRPG endslides that explore the endings of each companion, and how you affected the wider world.
Yea, IIRC DA:O did this and it made the end feel a lot more satisfying. You encounter so many characters and places, I think it'd help the ending feel fuller and more satisfying if you had some idea of what happened at the end, I was a little disappointed to not see that. The end felt very abrupt.
