I didn't romance Cassandra, but I couldn't make her divine. She was my bff and I selfishly need her with me AT. ALL. TIMES. Her being angry at things makes my world brighter. At least you get a choice.
Indeed. I'll honestly be surprised if they don't at least offer a choice for something bitter sweet here. That seems more unlikely to me than anything. They still have to think about their fans, no matter the story direction they take, and making anything linear and choice-less is just bad writing.
Of course, Solas is his own man and if he decides he wishes to ride things out alone, that's his decision. But making you fight him, when you don't want to, in a game where you could let loghain live, yea. I don't see that happening.
