Back to the topic, I'm pretty sure I've brought this up in the other romance improvements thread, but I'm actually quite partial to the approach where Tav is there to serve as a narrative tool rather than being, let's say, more roleplay focused, because I don't care so much about roleplaying a character in contrast to experiencing an interesting narrative and the world the devs have made for me (I will say I was a bit confused I could only be mean to Naaber, lol.). But this is very much a personal preference, there's definitely no harm in adding an extra option that is after all still going to lead to the same dialogue branches that are already ingame.
I am a bit in between. I do not care for Tavs/Durges because they are boring blank characters, instead I much prefer to have a focal/origin character, that I feel some kinship with, so I can think about how the story affects both them as well as their travelling companions while I play the game. Which is why I do appreciate dialogue that allows to portrait a wider range of positions and offers meaningful ways to influence the story or to show it from different angles. In the case of Astarion's act 1 romance, for example, it would have been interesting to confront him with a pc who is attracted to him but somewhat repulsed by or uncomfortable with the seducer persona. It would have been very interesting to see how he acts when his expectations are completely turned on their head.
For me it's mostly the cough-drop-voice and the lines said in it too, I think. The kitschy romance novel visuals (stepping out shirtless from behind a tree) are fun, but the voice is hard to endure. It gets even worse during the second time he invites you to spend the night because here the dialogue can be interpreted as being quite cruel.
When in the first act before the romance scene can this be seen?
When he showers you with compliments for the first time, there's a background insight (I think it's insight) running that can prompt the narrator to tell you that he is probably lying to you because his whole body language is just a bit too perfect and artificial.
I find him most charming when he talks about how to off you when ceremorphosis starts, or you fool around about the Wyvern poison Nelly gives you, or how he reacts when you tell him that he does not have Lae'zel's level of charm. It would have been nice to coax out this type of banter during the act 1 night together - the morning is nice.
