Damn, I had no idea this got changed. I loved the music in that final scene- it really captured the trauma of the moment, on top of the atmosphere of the location and everything that just happened. It felt like a perfect climatic song that captured all of the complicated emotions of finally killing his tormentor, and being a free person.
I'm disappointed that my friends who just got the game won't be able to hear the same song, which was only ever used in that scene, when they finally reach the Cazador boss fight.
Yeah, also my interpretation is that Astarion isn't feeling relief as this new song might imply, but is very overwhelmed and in shock at everything that just happened and that it's finally over but that it hasn't been triumphant like he might have expected, just an unloading of the 200 years of shit he's gone through + knowing he just disavowed the sun. IDK, there are nice parallels with the Aylin situation. Honestly I just think it's a huge cocktail of emotions and it's okay that he's also grieving everything that's happened to him at that moment without needing to reassure us it's all okay. I mean, when you talk to him right after that you can tell he's in shock and disbelief trying to process that it's all over, it doesn't feel real to him. The relief and reflection comes the morning after, where hopeful music is much more fitting.
The only positive thing I will say is that the song change has made me pay more attention to the shot where he's in front of Cazador's corpse, but at the same time that moment also feels goofy with the very strong instrumental playing and it gives me whiplash.
I'm also playing co-op with a friend that's playing for the first time and I'm sad she won't have the same experience I had, we're at the point where we're running out of quests to do in act 3 but I'm trying to postpone Cazador's palace as much as possible in case they hopefully patch this change out.
