It seems like the side-saucer design wouldn't do so hot in battle. Perhaps I'm on crack here, but it seems like it'd be far easier for an attacking ship to so an enormous amount of damage, assuming it was attacking from the same level. With the regular saucer structure a hostile ship has to get above it and face down and shoot to do the amount of damage that it would merely have to zip to the side to do to the sideways saucer, if that makes sense.
