I have to say, having finished the game today, while on the whole I enjoyed DA:I and got my money's worth out of it, the final battle is not even lackluster, it seems incomplete.
For example, when the (new) Breach appeared, it was jarring only because of 'convenience' what with my armies still at Arbor Wilds (yet there are dozens of men and women in armor in Skyhold just milling about), but that's fine and all, I'm not expecting complete continuity at this point.
However, where exactly was this? It's close enough to Skyhold apparently that they can see it, and there's a castle that Coryfish floats, but...how did the Inquisitor and company get there? Also, get there without any fighting?
All my companions were with me at the end, so besides the people I brought into the fight itself Cass, Dorian, Varric (which I should note only Cassandra only said anything during the entire fight, which was strange, maybe a bug?), what were the rest of my group doing?
Finally when Coryfish gets killed/sent into the Fade...was that...it? The connection between him and the dragon, I thought he'd at least...acknowledge the dragon died/he's briefly mortal? Anything really other than a smack and a death sequence really.
Coryfish I thought could have been a very deeply characterized villain (A type of Lazarus), and while evil, had some type of ending dialogue that could make the story deeper a bit more, but he kind of just despawned really.
