Then you really dont play the game at all ... Because now you just said the biggest bulls**t, that i ever heard. Yes, the Substrate doesn't really have a T2 AA, because that would pretty much make the attacking bombers useless... Yes, the Apollo is a great AA unit, BUT: 1 - fragile as hell, a single Punisher barrage kills it, and on the contrary the Apollo needs at least 3 or 4 tries to destroy it, but the Punisher is accurate, unlike the Hades, and the most damaging weapons of Apollo are inaccurate as hell, they miss a lot, especially its flak cannon... 2 - while the Substrate Sky Cleanser have considerably lower DPS than the Apollo, they comes a group of 2, and doesn't cost any radioactive, and can be created at really early in the game, while the other side needs an Armory, that cost radioactive and the Apollo too, and you only receive 1 Apollo for a price as much as you can buy at least 6 Sky Cleanser(and their shields and hp overall much stronger than an Apollo) and 6 Sky Cleanser DPS > 1 Apollo DPS.. 3 - If I'm not wrong, then the T2 Substrate Drone Hive can attack aircraft so that makes at least 5 ground based units in the Substrate side that can attack aircraft(ranging from the light frigates to the sturdy dreadnoughts), while on the PHC side there only 1,33 units can attack air (Apollo is 1, and 0,33 is the Mobile Nullifier, because it can attack land and air, but pretty expensive, fragile for its price, short ranged, a cost a helluva lot of logistics....
So i'm NOT FINE WITH IT!
