Some quick balance feedback:
Phase ships should almost always have Delicate Machinery--Alex did that particularly so that phase ships cannot outlast opponents (since they can almost always outrun an opponent of the same class).
The Agony Mk.II is, well...
- Increase the supply cost--even with substantial nerfs, this will be one of the best frigates in the game and should be 5-6 supplies at least.
- Cut the flux stats: Outside of the Monitor (crippled offensively by its slots), the phase ships, and the Hyperion, the best flux stats we get are the Tempest's 2500/225--this has 4000/350, a good 60% better. I would drop to something between the Wolf and the Tempest, depending on where you price it.
- Cut the armor, shield efficiency, or both: only the Omen and Hyperion have better shield efficiencies, and this has more than twice the armor of either.
- Increase the flux use of the Laser Cannon--this has the DPS of the Pulse Laser at 45% of the flux usage.
- Consider dropping some mounts--this is more heavily armed than any vanilla frigate, and none of them can converge five smalls and a medium forward (because face it, the Laser Cannon is a medium in performance).
- Remember that this is more mobile than any non-phase vanilla frigate (aside from the Hyperion)--it does not need armor, peerless flux stats, or loads of mounts to be great, let alone good.
Agony: cut flux stats, increase supply cost, reduce shield efficiency or armor, as with the Mk.II. The slots don't look too excessive, though.
Sorrow class: 3 supply/{day|recovery} frigates should be near-garbage--is this? Again, too much flux capacity for a non-phase frigate.
Despair: This is essentially a Medusa--same flux dissipation, shield efficiency, and mobility. Why is it 2/3rds the supply cost? (OTOH, it could use a bit more base capacity; it is little above half the capacity/dissipation ratio Alex prefers for destroyers.)
At this point I am going to stop looking at supply costs and flux stats--almost every one of your ships is too cheap for its role/quality, and I think your flux stats need a comprehensive look.
Revenge: FMR on a ship with four converging medium missiles? 16 reapers over a few seconds is crazy. This also has a lot of OP for a missile cruiser; Alex intentionally kept the Gryphon low to offset the large quantity of zero-flux weapons.
Weapons:
- Light Autoblaster Cannon: not crazily out of line, but if this is available why would I ever use the IR Pulse laser? Drop some combination of efficiency, range, or per-shot damage until you think that looks like a fair choice.
- PD Laser Mk.III: Cut damage a bit; +1OP and -25% range don't compensate for dealing nearly twice the DPS of the vanilla PD laser with much better flux efficiency.
- Tali MRM Pod: Nearly twice the total damage of a Harpoon Pod--I would drop it to 28-32 missiles.
