Sisko "just" an engineer?
Well, Sisko transferred to command early in his career after the then-Captain Leyton promoted him to lieutenant commander and named him first officer of the Okinawa
. We know of his engineering background because he played such an important role in the design and construction of the Defiant
, but it's not clear if he did anything else in addition to that.
But I agree that it probably doesn't do a character justice to downplay his background. The Romulans wouldn't send a nobody to deal with the Federation anymore than the Federation would do the reverse.
