I think the main issue with Halsin's romance is that he is treated as a "secondary" rather than primary romance option, and most Halsin fans seem to have wanted him as their primary option. Like I mentioned earlier on in the thread, I don't necessarily have an issue with him being poly, but the lack of content/depth, combined with the lack of establishing whether he's open to a long term relationship or not, makes him feel lackluster or even confusing as a love interest. (And his past trauma is a whole other can of worms).

It seems like all the poly stuff, rather than necessarily fitting with his established character, was for player convenience (because it basically assumes you're already in a relationship with someone by the time Halsin is available, thus the poly options for the most popular romances--Shadowheart and Astarion--and noncommittal ending).

I think Halsin can still be written better and more satisfactorily as a poly romance, I just don't think it's there yet as it is.
