Perhaps. But the game can be as dark as it wants to be, so long as my player character is a bright shining light in that darkness.
I am not too familiar with the DU questline - I haven't gotten far yet and generally have more fun with the other Origins - but I have a hard time imagining how to get the "dark" out of there.
I think that's the point. Kanisatha has made it quite clear since its reveal that he is very against the dark urge on principle and finds the idea of playing as it completely unappealing. And while I don't take as hard a stance as him, I'm on his side on that front. Although personally my thinking is still that Durge and Tav being the same was either never a thing and people are taking one or two scenes and extrapolating way too much, or if they were ever one and the same, then the original version of Durge was very different in practice. I would guess that if it were the case, Larian knew that going as hard with Durge as they currently have would be a turn-off for a lot of players. But when they separated Tav and Durge, they took that as an opportunity to do what they do, i.e, go way over the top to a stupid degree.
I think we who are criticl of this game need to accept something; there was never going to be a better versio nof this game. I fully believe that Larian put their all into this. They put their heart and soul into it, they pushed themselve as far as they felt they could, and this is the result. Which is to say, this is the best Larian can do. If they can devote so much time and effort and resources into a project and produce this fractured, spotty mess, then this is the best they're currently capable of, and we should give up hoping for better.
