Honestly, the best advice I can give for dealing with fighters is to largely ignore small weapon mounts and start finding ways to fit medium and even large anti-fighter weapons. Capital ships may be able to use small mounts as effective PD, but without the capital range buffs, other ships just don't cut it.
In general when I go against the Hivers I have a big ole tank ship to soak that has medium and large PD weapons for the fighters mixed in with a couple HE for the hiver ships. Then I flank that one with battle cruisers on each side and the rest cruisers. Destroyers/frigates just cannot stick in, unless they are super mod ones.
Devastators are pretty decent HE damage and locusts do pretty good pressure if you've got some something to deal with shields and armor. Same for Paladin PD.
And proximity mines. Never forget proximity mines. Those are quite nice.
Also, IPDAI hullmod is great. Almost all the benefits of the skill without a skill point.
All excellent suggestions, thank you for sharing.
I've been very skeptical of most fragmentation weapons since starting to play Starsector because while they excel at tearing apart hull my bigger concerns have always been getting to the hull in the first place.
I am a fan of frag weapons personally. You'll find them in all my faction mods and heck even the Hivers have a frag beam
However the persistent damage that the anomalies inflict from these weapons and the fact that they can be significantly buffed by building in the 4D Lensing hullmod led me to finally try these weapons for purposes other than PD and I really like them! Though I'm not sure I'd give the large mount version to my NPC captains as those have the potential for some extreme friendly fire incidents until seeing they get used in the simulator.
NPC's have gotten smarter over the years and I hope it gets tighter with future patches but yea sometimes they make some random decisions that boggle the mind.
There are also a large mount missile called the Skata, I think, that fires swarms of energy damage missiles that also create those anomalies, though I'm not sure if they would be quite as effective against fighters. Though, to be fair, I haven't tried using them for that yet.
I had to look that one up but yea the LRM line of weapons in general have a warm place in my heart. Being a pure salvager I do not come across PRV weapons much in my game so I'd be curious of your results.
Thank you both for contributing to the correspondence. I have noticed a sharp increase in downloads after rarr "saved humanity". I am sure Warnoise is not the only player that has freshly installed the mod and thought, OMG SWARM???!!!
