This ended up much longer than I had expected but I'll keep it and hope someone else enjoys reading of failed attempts as much as I enjoyed coming up with and trying them.
I'm still trying to get a functional approach to this thing, though I'm fairly certain I have a plan that will work Main issue is that I'm limited by my commission with the Sindrian Diktat.
My first attempt was with two Conquests and two Astrals. It started off well enough, until the AI Conquest got obliterated as I hadn't realized it was tanking the station to allow the Astrals to do successful khopesh runs against one of the corner weapons pods. The second attempt was with one Conquest (my own) shifting in and out of focus of the battlestation supported by two Astrals (Still Khopesh and Longbow) and three Herons (loaded with wasps and gladius squadrons to provide some cheap target that could both swarm the station and provide a screen against the Flashes). That went quite a lot better though still failed as a result of mispositioning on my part and the increasingly saddening fact that I STILL haven't managed to get the Hardened Shields hullmod for the Conquests (as with it I have a feeling I could legitimately tank the battlestation, with some flux management, whereas right now that 1.4 flux/dmg ratio is painful).
Returning to the commission limiting me: I'm pretty sure it would work out fine if I had an Odyssey or a Paragon to simply soak damage to shields with a good ratio while the Astrals and Herons bombard the outer edges until I can properly approach and broadside it with the Conquest(s). If that fails, or if I simply get too impatient trying to salvage one, I'll probably get around to salvaging absolute metric tons of cheap frigates/destroyers and take the Stalin approach...
Did have a passing thought to grab a couple Onslaughts, arm them to the teeth, and simply burn drive right in and raise hell but I figure they'll simply get ripped to shreds by the sheer damage output of the station.
Oh, speaking of Odysseys and Paragons, will the Tri-Tach markets around Hybrasil spawn fleets with those? I've seen Astrals (and that's actually where I got the second one) but have yet to see either of those flying around.
This game is great, I'm really enjoying the challenge of coming up with a fleet setup for and subsequent attempt at actually putting the plans into practice against it.
