I'm reasonably sure that like in other games, any German VA would be so far below the English VA in quality that I wouldn't want to listen to it after playing with English VA. Also, the translations of terms and names of D&D worlds are sometime really stupid and at the very least unauthentic.
So, while I would like to play BG3 in my native language, I have yet to find a game where both the VA and the translation are satisfactory. TW3 did the translation very well, but some voices were just not very good. I would not expect German VA for BG3 to be different.
