Light Needler: It costs as much as a medium weapon, it is okay for it to perform like one. I guess it (and Railgun for that matter) competes with other mediums because it is not as slow and inaccurate as Arbalest and Heavy AC. In some cases, I may prefer Railgun over Light Needler.
Harpoon: I usually unload two or three at a time because one missile is unreliable and even if it connects, it will not kill most ships at full hp in one hit. Harpoons are not very useful to begin with unless spammed against a relatively defenseless target.
Sabot: Maybe it is a bit strong, but it better be for the OP cost and low ammo I put up with. Unfortunately, AI does not use them optimally like the player can.
Hurricane: I have no problem with how fast it fires. If anything, I am annoyed with how the AI wastes them. Hurricane is simply large Harpoon. That said, I would not mind slowing down rate if the missiles regenerated like its second iteration. Even as it is, I prefer Locusts over MIRVs anytime - just as lethal against small or armor-stripped ships, but much more reliable, and enough ammo that the AI can spam Locusts if it wants (which it does not always do).
Fortress Shield: The change seems unnecessary. Especially since Fortress Shield can build up more hard flux than tanking a few hits if left on for too long.
Damper Field: Like TaLaR, I see no reason to use this with the changes, except maybe on Mora, who can be built unarmed aside from fighters, and probably benefit from the change. Mora might be unaffected by no dissipation since fighters can do all of the work while the Mora chills out in its shell. For frigates, venting seems like the superior option either way. Aside, Mora has clearly hijacked Damper Field from Centurion, and Brawler should get its original Ammo Feeder System back, and Centurion should get a different system.
Talon wing: This is one change I can agree with. With the current fighter costs, Talons are too strong for 0 OP, but they clearly are not 8 OP strong.
Claw wing: Claws are not overpowered, and I see no reason to change this. The only reason I can see to change Claws is Xyphos looks horrible in comparsion. (I think Xyphos is underpowered for its cost.)
Kopesh wing: I think current Kopesh is fine.
Terminator: No problem with Pulser Terminator either. Sure, it is annoying, but it merely uplifts Tempest a bit from simply being a fancy Wolf with omni shield but no skimmer. However, I would not mind the change if the Tempest could deploy two or three Ion Cannon drones at a time. Only one, keep the Ion Pulser.
P.S. Tartiflette's changes may be fine for a tourney where the fleet only needs to fight one battle against an equal-strength opponent, and can afford to gamble on a missile spam to sweep the other side away if unprepared. We do not have that luxury in the campaign. At best, we fight an equal strength opponent at max CR. At worst, we can fight against superior opponent or a gauntlet of multiple encounters and suffer CR attrition. Oh, and we have resources to deal with (but the AI does not care), and we do not always want to go all out in every fight. In cases when we have the advantage to begin with, they run and we can auto-resolve for free spoils.
