I personally feel like about 50% of the time, my character is making faces not even remotely close to whatever reaction I'd imagine them having. If I could wish for something without regarding to the work or money behind it - then it would be some kind of pre-set animation personality. Kind of like how you choose your animation kit in PoE2, but yknow... Included in these cinematic sections so we don't have, like Blotters example above, a Lolth-sworn drow making weird faces when encountering death...
And thus, I can only imagine how I'd feel regarding full (or at least more) voicing for non-premade PCs if it is anywhere near the PoE2 voicing... I still feel this mix of cringing and laughing whenever I think of my character randomly screaming "RAAAAAAAAAWWRRGHHHH!" when I start shooting things... I literally went through every single voice option in PoE2 and almost died out of laughter every time my character randomly went screaming. That is not quite how I imagined my silent, sneaky ranger to approach enemies... :') Meanwhile, I'd say the voice acting in Pathfinder is a rather good "medium" option, where your character interacts and talks (out of dialogues), but in a more... Subtle and neutral way. Like our Tav does right now.
I am not to worried about bad quality VA in this game, given what I have seen so far. As for the facial expressions, I am hoping either way, whether they go voice on the PC or not, these are just placeholder key animations and will be corrected before launch. Keyframing is a bitch though, and it takes a while. Especially for facial features to get them right. So I can see why they would just put these quick animations on the face until they got them better.
