The expressions were dead dove.
I have already seen more than a few new ways to HC the new kisses for ab*se RP. Many have even said Tav still looks scared, surprised, or like they're faking for Astarion because they're frightened. RP is still possible with these new faces.
So do you think the new animations allow for different ways to rp them because Tav still looks frightened in some places, or that Tav shouldn't be allowed to look scared because that would be dead dove content? If it's the second one, why are you happy with the new faces? If it's not, why should the old faces not remain an option?
Leaving it in the game still leaves the possibly for people to stumble onto it unwittingly. To me, this is not a question of RP. It is a matter of leaving dead dove content out of a gen audience game, where players do not go into it knowing what they're getting into.
For players who saw it as dead dove or a tragic romance, before or after Patch 6, forcing their Tav to look ecstatic wouldn't change what they see in the romance. It would just not allow them to roleplay in a way that feels appropriate or comfortable to them anymore. If the original expressions were locked behind one or multiple dialogue choices of Tav expressing fear, nobody would have to stumble into content that upsets them.
