It's a small thing, but seeing as they're assault weapons first with secondary point-defense function, it's a tiny bit annoying. But maybe that's just me.
That's just the way Advanced Targeting Core is, friend.
Dislike the effect exerted upon Misery and Bane? If you prefer not to wait until Deathfly can consider the issue in detail, try removing the "PD" and "PD_ALSO" flags from both weapons, as seen in the "hints" column at the far right side of the mod's
weapons.csv file. Re-save the file, and you're done.
Of course you can't have your cake and eat it too. With the above changes, those weaps will lose all of their automated PD utility. Against missiles, that now means manual targeting only; good luck with that.
Personally, with such slow shot speeds and even slower turret rotation speeds, I don't consider Misery and Bane to be very good point-defense weapons anyway. At least they do have a rate of fire that's decent for attack purposes.
But when mounted aboard an ATC-equipped ship they will now share in the 200% range buff. You need to decide which use case is preferable for your playstyle and tweak (or not) accordingly. Enjoy!
