I agree with you, but perhaps the localizers don't have such a rich imagination and sense of the game world?
I understand why you understand them, but it's one thing to make videos in your free time, and another to do it with a team of professionals.
Although, I must admit, I really like the set of sounds (not voices) for the creatures of the Sanctuary. The only exception is the mermaids, to whom they later added terrible victory cries. But as for the snow maidens – it's a direct hit, perfectly chosen, I was very pleasantly surprised by them.
