I will likely repeat my self from the Solas thread, but I feel the need to sum up my rather messy thoughts. I also have not read all posts in this thread yet, so I apologize if I'm repeating anyone else.
Something big is coming - bigger bad. I think it is connected to the blight - maybe. If Solas wants to save the ancient elves it is something that is threatening them. If he wants to restore modern elves to past glory, it's a threat there too. Flemythal knows what the threat is, she wants it dealt with too. So it's probably bad for everyone.
I can't remember where, but someone from BW once said humans in Thedas are corrupted - maybe they are, more so than non-pixel humans? Their mere existence might be a problem or a hindrance to whatever Solas is going to do. Modern eleves are not what they should be, dwarves are not what they used to be and qunari might be a crazy genetics experiment. Scary if Solas is ruthless enough.
Solas, seen in light of the spoiler, is not only morally all kinds of grey, but is a man on a mission. We knew that, but now it has real weight. A strong sense of purpose coupled with greyshaded morals? This has a fantastic potential for complicated, even more than I originally thought. Personally I love it, but I do hope there is a redeeming path. Drama is coming!
