My initial ending was the “Trick Solas” ending and it felt very satisfying seeing him get his comeuppance.
Then I did the “Talk Him Down” ending. And I can definitely see how people who played Inquisition with Solas as their love interest might enjoy this ending. But for me, Solas is not redeemable. He killed Varric. He betrayed Rook *repeatedly*. He would kill millions over his regret.
Then I did the “Fight Solas” ending, and I felt a thousand times vindicated in my original decision. Solas utter contempt and true feelings finally come out. He spent a game and a half telling the Inquisitor and Rook that they were NOT gods. But in his moment of defeat his true colors come out and he lashes out saying I AM A GOD. Yeah. Fuck Solas. All my homies hate Solas.
