The thing about the dalish is that they will never be what they were in Solas’s time, and that’s okay.
The dalish taking pride and wanting to learn their history is fine, it’s great even, but cultures evolve. Cultures change dramatically over time. No one can realistically expect the dalish, or elves in general, to be what the elvhen were. The elves have been through so much crap, and have lost so much of their culture. They’ve rebuilt some of it, and it only resembles what it was, but that’s not a bad thing. Cultures change. Both the dalish and the city elves have a unique elven culture and neither of them are “wrong” or even more right. They’re just different.
And I think this is my main problem with Solas. He’ll try to drag down everything the elves have struggled to built because they’re wrong to him. He will try to make them his version of right and completely disregard the fact that that is the very last thing the elves need.
The elves need people like Briala who will fight to secure their future and Merrill who will put to use the knowledge they have of their past. They don’t need Solas coming around and destroying the little they already have and reminding them how “wrong” they are
