Facing a large army of frigates and/or scintillas, I like to do a fighting retreat from the top of the map to the bottom. That pretty much ensures that:
- I don't get badly surrounded
- I don't get ganked up on by fighters
- I don't lose out on killing speed early on, e.g. I can usually collapse on the initial deployed force with my capitals from 2 sides; and then the northern side turns around to deal with the reinforcements. Initial kills get quickly replaced by fresh enemies, so my ships get full uptime on their guns.
- As I retreat further backwards, the reinforcements for Remnant take longer to reach the front line, giving some breathing room during frigate phase
- Generally, this means that I end up killing Scintillas as I come back up from south to north, after dealing with the frigates.
There isn't that many of them alive by that point, though. I think their AI moves them into capital gun range, when they're giving chase; and they seldom make it out. By the time I'm done killing Brilliants and Apexes get to come out, there's maybe 1-2 random Scintilla remaining.
On another note, I was running 2x Executor 2x Radiant, and I gave each of the Radiants one Paladin PD. They're entirely capable of spending their flux and more while using one of the slots on the PD, and with s-modded Extended Magazines it isn't actually bad damage(mediocre range soft flux energy, but efficient).
The thing deletes fighters and missiles very fast, which also makes the ship AI not fire the big guns on the small stuff, not turn around unnecessary; overall while it didn't feel like a mandatory addition, it enhanced ship behavior to where it made better use of the rest. For example, swapping the PD for another Autopulse or HIL was not an improvement. Over the entire engagement one PD would kill 300-400 missiles and 80+ fighters, over half the fighters and 80%+ of the missiles the entire ship would destroy.
And it trivialized dealing with fighters. Maybe those Scintillas would make it out of capital range, if Radiants were wasting more time hitting fighters with beams and Autopulses.
Not sure if there's something like that that could fit on an Executor, though. I wouldn't want to use something as a PD if it wasn't capable of clearing fighters / missiles before ship decides to turn in that direction and fire main guns there.
