Such an interesting article here on representation of gay characters in Bioware's games, and why "unrealistically" positive portrayals of same-sex relationships can be a good and powerful thing. There's a paraphrased quote from David Gaider that I really like.
The author wondered whether ME and DA were presenting a setting that was all sunshine and rainbows, in the sense that gay relationships were unremarkable and entirely free of stigmatisation and the other issues that persist in the real world.
David's paraphrased response was:
"Sure, he said. It is idealistic, maybe even simplistic, to make a world in which gay characters roam free. But is that really such a bad dream to have? For players looking for a rare chance to experience this dream, the fantasy can be just as powerful as one about slaying dragons."
Definitely recommend reading the article, it's well worth your time.
I'm also interested that Dorian as a character is sort of changing up their traditional approach by introducing us to a setting in which his sexuality does attract criticism, misunderstanding and, perhaps, ostracisation - but he's entirely unapologetic about it all the same.
