I've noted a few things related to the Antique section of ships & weapons from this mod that I've currently found during my most recent playthrough.
1 - The Sacciform Area Denial cannons don't reach their indicated range, and dissipate at 500m, instead of the 1000m indicated within it's stats card. Is this intended as to their function of split-shot AD weapons? Do they also benefit from ECCM (and other missile modifiers to speed/etc), thanks to their slightly guided nature?
2 - The Verisimilitude usually runs out of PPT (Peak Performance Time) thanks to it's system's nature and high spamability, thanks to the AI's usage of it. Is it plausible the PPT hit on use of the system only happens during engagement of the opposing forces, or generally gets nerfed so the Veris' can get some kills in and not run out of PPT so fast?
3 - The Serendipity I've found tends to crumble under any reasonable amount of fire, thanks to the lacklustre speed, lack of good armour for a brawler and the nature of it's phase cloak/skimmer combo.
Extra - On the other end of the spectrum, the FaysCo ships are somewhat reasonable, with the Alcott being one of the most, if not the most enjoyable phase ship I've had the pleasure of using, outside of the Interstellar Imperium and Holy Covenant of Kemet. It has insane speed capability, ensuring almost nothing will escape it's ire, and in capable hands, the previously lacklustre looking loadout has sheer capabilities of crushing even light battlecruisers. This can mainly be attributed to the Shift Jets system (which for clarity I'll call Thundershift Jets, to not confuse with GMDA and some other mod having Shift Jets) giving it insane speed (except backwards), therefore allowing it the freedom to get in and out of trouble when the ship's captain and crew desire so. There's maybe one other ship capable of such manoeuvres, and it's the Verisimilitude. However, unlike it's destroyer cousin, the Alcott doesn't eat it's own PPT like it depends on it, and is also a phase ship.
Overall, this mod is quite solid, with some interesting ships that cater to fast, brutal playstyles, and definitely one I'll continue playing with. Good job!
