I think the game could use a more initial fragility. I love leaky damage, no matter the game. Non-leaky makes it a game of focus fire to actually knock ships out of the fight; with leaky damage, spreading your fire out can be a valid tactical option for degrading enemy systems.
That could take the form of 'concussion' damage from normal hits, or perhaps an inner/outer hull mechanic that leaves some systems partially exposed to weapons fire (engines, weapons, sensors) while others require armor penetration (life support, reactors, magazines).
