Reduced Bomber HP + increased build time - viable answer to Bomber Spam?
It's well known that bomber-carriers become the best subcapital and the lategame, with sufficiently large numbers able to readily overwhelm ships like a Flak Burst Kol that were intended to counter them, whereas the subcapitals suited to face them - light frigates and flak, get shredded by titan AoE in the lategame.
So consider the following change - bombers lose 33% of their HP, and their rebuild time is doubled. Right off the bat, this increases the effectiveness of flak and fighters, and the Kol gets improved utility (though Vasari Bombers could still avoid dying to the first volley). This also means that if you lead with fighter-carriers and flak, your opponent will have a harder time rebuilding their bombers after you bring in your capitals and titan.
Downside is, leading with anti-bomber subcapitals potentially leaves them exposed to enemy titan AoE - but then, if your own titan can enter the field without worrying about the bombers your opponent spent so many resources on, that might be worth the sacrifice.
