Well, it wasn't Hobbes' fault that Tolwyn gave him all the credit, and he almost always got to Olympus on my wing, so it probably depends on flying style and dumb luck. Of course, the really annoying thing about the Olympus mission is that you start off face to face with a Kilrathi ship (was it Grikath or Sartha? I can't remember, but either way it had neutron guns). To make things even worse, the Concordia has a CAP, which kills me more often than the Kilrathi.
I always wished that it was possible to finish WC3 without killing Hobbes. And I still reckon that it was his "evil" self that was the overlay.
