What crazy fans!
I can't imagine Russian speech in scrolls.
In general, English speech is always better. Of course, I'm not talking about movies.) Although, in movies, English often sounds more beautiful.
Localizers often can't support the atmosphere that was originally intended with their voices. This is in those rare cases when the voices in their games don't cause vomiting.
For example, the Tau Commander in Dawn of War was voiced by the guy from Postal. I'm not arguing, that voice suits the guy perfectly. But it's just terrible in Warhammer.
Fargus translated it amazingly, and I have huge respect for him. And yes, even the play on words "GEK and gecko" was preserved.)
Well, in general...
The situation here is the same as with Russian books.
If a book is not a stupid Russian detective story or a terrible piece of science fiction, then the names in it are usually foreign.
Because Captain of the space cruiser "Doctor of Sciences, Professor Schwarzenegger" Ivan Fakov or Misha Zislis just sounds like utter nonsense. Or trash.
