I think the damage-to-health ratio is at exactly where it should be now. The thing I was always complaining about is the ratio in other space games, in which ships punch each other back and forth ,taking hits like medieval sailboat take cannonballs. This, in my opinion, completely eliminates the sense of modern-ness, let alone science-fiction.
I'm talking about that smaller ships really should just take out a poorly defended enemy with just a few shots onto a weak point on the hull, this makes the game more hardcore and differs a lot from all other similar games. No need to buff hull at all, increase combat range and reduce hit rate instead is a better option.
