I'm completely against it.
It goes against all that AA represents.
People already aren't happy that Larian is watering down AA. Dear Larian, please, go and read places that represent people's opinions better - Reddit community, for example, has 2.5 mil members.
As AA fan who loves this route BECAUSE he is evil and abusive, I don't need to see him being submissive to Durge, because it goes against everything this character represents. This would be an assassination of AA character. His entire point is that HE NEEDS to be in control. He breaks up with Tav/Durge who doesn't want to become his spawn exactly for this reason. He would never EVER agree to submit to anyone again. Even with 99 intimidation check. This is the entire point of his character.
Dear Larian, please, stay true to your vision of this character and focus on his much more important present problems like lacking the endgame kiss and having the same approvals as Spawn Astarion. He also has bugged epilogues with Illithid Tav.

Number one priority, in my opinion, should be giving us an option to choose Tav's expressions in AA kisses before any other possible fix to his romantic scenes - I'm on console and I can't even mod away those (awful for me) happy expressions which trigger me so much that I can't play this romance anymore.
These are much more important issues to fix, in my opinion. Abuse is not the topic you can simply and easily dismiss. You need to deal with it responsibly. Enough people are already saying that Larian romanticized and normalized abuse by making Tav look happy in AA's kisses. I don't want to see my favorite gaming studio get cancelled in the future because of it.
Dear Larian, you need to deal with the problem of AA's kisses animations ASAP, please, don't make it even worse than it already is for a lot of people.
