Another thing I'm in favor of, if it's something that can get everyone to agree on even regarding expressions, is to soften AA's kiss animations, since they are perhaps the thing that trigger the most. It was a proposal that had already been put forward in the other thread about patch 6. I personally like AA's kisses, but I'm absolutely not against changing them.
As someone who plays both Spawn and AA paths, I'm absolutely against this, because Larian has already spent a lot of time on AA, changing his kissing scenes without paying much attention to Spawn. In Spawn path, still only 1 new kiss triggers (and with a horrible angle) while all the other companions have 4-8, including AA with plenty of kisses and lines. Both Spawn and AA still don't have any endgame kiss. But both "happy" and "scared" animations already exist, so just adding an option means 1 boolean flag, which won't take much time or effort, which should go now to Spawn's path to even him out with AA.
Also, after thinking about it, I absolutely agree with BlueScaliesxx98: both sides deserve to have their expressions in canon, without the need to search for mods. Mods can get deleted for various reasons, including their own author taking them down. It happens, it has happened before. People, who are now triggered by happy expressions, shouldn't be dependent on something which is not in the game itself.
