As for me, a points system is adequate. It is true that sometimes pisses me off when I will take 80% of your opponent life points and ally meanly shoot. But as-or less learned to endure.
Would be nice that the shape of your ship change according to your equipment, like if you have more hull it looks heavier and if you have more shield it looks more tech. Also if you have extra speed the ships looks more aerodynamic or missile pods vs mines dropping system.
