Yeah, this was a Nexerelin Pirate playthrough, so burn 10 was actually helpful at times. I agree with you that to optimize it for combat you should S-mod in the Hardened Shields, I think. I would personally probably just use the rest for capacitors, can't think of much that would benefit this ship more. Armored weapon mounts and then mounting HACs if that helps with the accuracy could be another consideration, since it would be +100 range. But I can't be bothered, because it is good enough as it is, and if it makes travel go faster then all the better.
It was a Pirate playthrough, before I started my own faction and conquered Sindria that is. Fun fact: Phillip is still there and still Supreme Executor, and I am still not important enough to petition him.
