It seems you have the same idea as mine
Based on this rule of mine,the only thing that changed is the rule,no construction rule of jumpship,warship and spacestation needed to be changed.
We can just write fluff that the structure that support the armor of warship didn't just contain structure support and KF bloom support system,but also impact dampeners and heat absorbers.
Of course,the bigger the ship,the more damage reduction system you needs.This will give small warship some advantage over bigger warship as they can get tougher with less SI(And by that I mean SI that weighted 20% of a 500000tons warship give as much resistance as 35% of a 1000000tons warship,or something similar)
Other than that,anti-fighter weapons should stay as anti-fighter weapon.Thank to the damage reduction system,standard weaponry tend to be ineffective.Standard weaponry on warship when used to fire at warships(any kind) or even super tough dropships(Maybe having more than 500 tons in armor?) need a roll to hit first then another roll to see if the hit is effective(Maybe 9 for tough dropships and 12 for warship),to represent lucky hits on the structure.
Does that mean fighter is just fly now?Of course not,fighter is small,that means they can spot weak point in armor easier(especially if it's a warships shaped like a giant crab).Weak standard weaponry might do zero damage if the warship can reduce that much damage,but still can make critical hit(At chances of 12 if the warships is REALLY tough).Bigger guns can do damage but the further they are from the warship,they less chances they have to hit weak points(Again,roll first to hit,roll another to see if hit is effective).Any weapon that deal damage with lots of projectile(HAG,LBX,SRM) will most likely do zero damage and zero critical due to low damage.
We should also have two kind of damage reduction which I get inspiration from the Fallout series.Damage reduction and damage resistance.Damage reduction reduce damage in percentage.Damage resistance reduce damage with point and can withstand attack if the resistance point is equal or higher than damage point.
Damage reduction should only be used in capital and sub-capital weaponry attack,while damage resistance should be used in both.The damage deal by standard weaponry after getting resisted and reduced is just too low to worth the trouble of using fighters against warships.Damage resistance for both capital and standard weaponry should be different,to represent that projectile of NAC and beam diameter of NL used by warships are HUGE,so more damage reduction system can reduce the damage.
In fact,it's perfectly possible for warship to withstand NL hit with zero damage.
For nuclear missile,ANOTHER damage resistance AND damage reduction number is used,because nuclear weaponry always caused big explosive that effects wide area. :D
My 2 c-bills.Although I feel like I make warships OP now :D
