As I and others pointed out, you have a lot of interactions based on your race and class. I'm not keen on playing evil characters, but I don't think, I miss out by playing Tav instead of Durge or an origin. Durge just has different interactions and - since I was spoilered there - a connection to something specific in the old games, which I think, might even be presented better here, since I never felt like I
was a child of a murder god, who has to fight against their nature
in the old games. So in fact the Durge does do that better imo
