For some reason some people are against naunce. Anyway, the writers are aware that the evil route needs far more development. Kevin outright said it on stream. So Azarhal is clearly the minority in this case considering all the threads across the forum and reddit about how poor the route is.
I stand by my opinion that the evil route only appeals to people who enjoy basic murder spree and drow sex. I have seen little that would make me change my opinion.
No disagreement from me there, then. My main worry is that there is no bandaid fix for this path and that is reveals a weakness in the overall plot of BG3 Larian cannot fix without letting players experience the whole thing start to finish. DOS2 has this problem too. They could make the same mistake here and we would be left with a highly polished Act 1 that then falls apart when you go to Act 2.
