In STO, Vulcans don't make good science officers.
Not really sure how Cryptic managed to screw this one up. I guess they figured the narrator wouldn't have made a good science officer. He is a politician after all.
In 28 seasons of Star Trek TV series and 11 movies, we've seen exactly *ONE* science officer who was both Vulcan and clearly demonstrated to be competent, and he was half-human. Who says they messed up?
