The main problem I have with Halsin is it all of this feedback, while valuable and insightful, feels very much like we are trying to figure out ways to explain and/or justify Halsin's character and behaviour after the fact. I understand that this is what we have to work with, but there some part of him that feels permanently tainted because I dont think this kind of thought and care was put into his character by Larian and his writer. I dont like the idea of being given poor quality content, and trying to find any and every way to try to make it seem like its not. Im not sure how I feel about trying to work around what we were given just because it was handled SO badly. This doesnt seem to be the first time his writer has done this and it diddnt seem to be too popular with his previous characters, but people made it work after the fact becauae it seemed consistent with the character. Which is fine, but I think this incentivised his writer to not listen and keep doing what he does, maybe even more so, and we got Halsin as a result.
I would prefer the non monogamy and drow aspects just be dropped entirely, mainly because they were handled so poorly that I think they are potentially actively harmful, and it doesnt seem to actually add anything of value for the audience as far as representation especially given all the backlash. I think the vast majority of people who wanted Halsin as a romantic partner diddnt have poly even remotely on their minds anyway and it was clearly added as a gimick for a small minory of the audience and for Halsin's writer's amusement. Since all of the bad stuff was contained in act 3 I dont think dropping them would create a whole lot of extra work to fill in those gaps in his character. Especially if there is unused content ready and waiting. Also get rid of the bear in the intimate scene because no one actually wants that.
I would prefer they just expand on what was given in acts 1 and 2, because thats the character everyone wants anyway. We just need more content in acts 1 and 2. There are plenty of that Halsin present in act 3 as well, all of that can be kept in, just need to fill in the gaps. While I love the idea of being able to go with him to help the refugees and orphans, I would also like the option of just going off with him somewhere as a couple.
Also I would like to see him whittling, smoking his pipe, and/or writing in his journal in camp.
