I think everyone should be able to choose how Astarion kisses Tav/Dark Urge. Astarion always loves his romance, regardless of whether it's Tav, evil Tav or Dark Urge.
For me, the story between the Dark Urge and Ascended Astarion often doesn't fit, even though they should complement each other perfectly. They share a similar fate, understand each other's perspectives and support each other in every situation and, depending on the situation, they are similarly power-hungry and cruel. And yes, my Dark Urge also puts up with his jokes, although he's funnier when he doesn't want to be funny. And then come the moments where Astarion tells complete nonsense and the story goes to hell.:(
I see. I played Dark Urge on my first playthrough as well. Which of course surprised me and I immediately saw that murderous side in Astarion more clearly. “Killing together is a bonding” thing. So a small but effective genocide of 7k vampire spawns... Yeah, I have some bit sadness that Tav and DU can't make references to Astarion's past phrases - that would be interesting for the novel. Maybe it's there, in the text, but as a response to Tav\Du hm.
For romance, it was best to add “I love you” phrases for each companion.
However, at this point I want the face in the kisses to match the meaning of February 14. And not to be changed again. Especially since the author of Astarion left Larian. I'm not sure about the unrealized ideas that didn't have enough time. However, when adding something that wasn't known - it would be a question of whether it should have been that way anyway.
