Doubled maintenance cost, one less flight deck, the ability to have four flight decks and various weaponry disabled for the entire rest of a fight, and a much lower extra crew capacity for absorbing fighter losses aren't downsides?
Same deployment cost, more than twice the hull and armor thanks to the twig parts, much better drones, almost twice the speed and maneuverability, cheaper, smaller skeleton crew, better PD... We can play that game a long time, and in the end you still won't make your point relevant, and you still won't get any of the changes you want. What you did managed to antagonize many modders with that impressive display of egotistical entitlement.
I was gonna say that the Keto has the benefit of being at burn speed 8 without any expensive hull mods but then I checked the numbers and with a deficit of 85 OP you could put several hull mods on the Astral and still have more OP for weapons. I get the Keto's gun is supposed to offset this but in my limited time with the Keto I've found the main gun...well it's been a dubiously useful proposition in capital scale battles, since it lacks frontloaded damage and the AoE EMP tends to just go into shields all around.
The Keto might need a few smaller buffs to offset a hit as big as knocking down the burn speed like that.
The Keto has 50 spare points once the slots are filled with average weapons (knowing that Scyan weapons are actually bellow average cost), plus 1 large and 6 small built-in, against the Astrals 90 spare points, or 55 if you want the augmented engines to match the burn speed. And then the Keto has still far better stats and doesn't need those hulmods that much. Also the EMP from the main gun pierce shields outright and can silence a target with ease to help a bombing run.
