I enjoyed the BG3 narrator from what I have heard. And I think she fits the tone of the game really well.
THAT said, in unlikely case Larian would tackle Polish dubbing (which I don’t think they will for that size of VO) nothing would bring me more joy then hearing Piotr Fronczewski narrating BG again. I even played Torment: Tides of Numenera in PL for a bit, to be hit by this sweet nostalgia of Fronczewski’s deep voice.
