I gotta say my elven characters - who are doing everything they can to make things better for the elves - are pretty pissed off about this. 
I can imagine. Probably mages, too. Never played either myself, but if I had, I'd want to rip Solas up one side and down another for that alone, for the way his actions make it worse again for "my kind".
I hope we get to see a real change in Thedas, in terms of the power balance between the different races. While throughout the series, some small things change, the larger world stays very stagnant.
So much for the world being forever changed, eh? It was a big disappointment how Trespasser basically rolled everything back to square one and invalidated most of what we thought we had accomplished. As I said in another thread, I'd actually like to see this setting turn from generic medieval low-magic one to a really spectacular high-fantasy one with ubiquitous magic, spirits everywhere and all. It wouldn't be a utopia, there would be an incredible chaos even if the Veil came down "gently" and the shock didn't kill everyone, but it would be something different.
