Thanks for the detailed answer. I see why it's confusing now, apparently our idea of what the old meta used to be isn't quite the same. I wasn't aware people considered any specific defense module configuration meta, seeing how they all lose to naked designs anyway. It actually made my patch back to 1.6.2 (equivalent to 1.7.4) just to confirm again that in fact 422BB lose to naked battleships and they do. Do or did people really consider 422BB the unbeatable meta ship design in 1.6/1.7?
In any case it's getting kind of late here, I'm wrapping up for the night. I've ran a lot of test cases against the missile steelman (4 shield, 6 L-marauder, no whirlwind) and didn't find anything that could beat it, 422BB came the closest but still didn't win a single time. Depending on how much time I have tomorrow I might consider further testing but for now I'm convinced.
And kinetic weapons against shields are still a mess. They kill their first target cause that they all focus on still. From then on it's clown fiesta, every time they accidently starting dealing hull damage they quickly switch away to another shielded target.
Edit: At long last. One last test. I'll declare this half a success but 6 L-missile 4 shield has been beaten. The trick is ignoring missiles, they're a distraction. The real problem is that most weapons just suck dealing with regenerating shields, especially anti shield weapons. Missiles just end up being the weapons least affected by this is why they're otherwise dominant. It's not cause missiles are so good (well they are really good), it's that 4 shields is the superior defensive option and they happen to be the best response. Well. Second best response.
I freely admit that this design is not my idea, rather someone else posted the idea on this forums a while ago. I thought it was interesting and now just remembered when thinking about how shield regen was the real problem.
The next step would be testing if that design was good at beating other designs as well, but seeing how it's protected by the almighty regeneration bubble I actually think it can.
That's really interesting, full shield piercing is an interesting touch! I've been testing for the last few hours and came to similar conclusions that you already stated, but I'm really happy to learn about that battleship design. That's actually quite close to what I used to fight the Contingency, except I filled out the weapon slots with I think kinetic as well as point defence and bombers, which left me with less shields (but the major source of contingency damage is arc emitters, not their escorts gamma lasers). You seem to have enough energy to employ point defence - is the reason you don't have it to lower the battleship cost? I feel like you could add it and it would end up better, I'll test now against 6L missile
Edit 1: the point defence adds a whopping ten minerals to the ship cost, and takes twenty power out of the ~70-80, I think it will do better, time to see!
Edit 2: the results were unshield 23/50 dead (27 surviving), all steelman dead. According to the AAR, my point defence killed 1555 missiles, and one of the more amusing things about this battle was that the steelman total damage output (216370) was higher than unshield (206752). I did it with 50 each because my computer sucks and I'm impatient, but I'll now try it with 102 vs 100
Edit 3: the results were confusing to my simple brain. 100 (unshield) vs 102 (steelman) still had unshield winning, but they only had 50 ships survive (exactly 50%, obviously), lower proportion than before and old mate got, despite the fact that AAR says the point defence killed 2885 missiles. Still, definitive win for unshield. I shall now test unshield against other types of battleship.
Edit 4: Unshield vs 422BB had me thinking the entire fight that Unshield would lose, because it was losing ships fast and heavy early on, and even when bombers arrived at the 422BB ball 422BBs didn't start dropping. It was a very close fight, but Unshield won, with 35/100 ships surviving (and 422BB losing all 100 ships). Will now test against the different missile cruisers/Swiss army cruisers.
Edit 4: (I'm using equal fleet power btw, because I can't be assed calculating costs and I'm terrible at math. I know it's not a good way to calculate it). 100 Unshield battleships against 200 torpedo/missile cruisers, the Unshield battleships have 1 Guardian 1 Flak PD, the torpedo cruisers have one swarmer missile and otherwise all marauder/devastator. Side note about this battle, the "fleet power" ingame calculators thinks these fleets are nearly exactly matched. The results are that the torpedo cruisers win, with 97 out of 200 surviving.
Next I tested the Swiss army cruisers (once again, equivalent naval cap, and the back plasma swapped out for swarmers). The results are that the Swiss army cruisers win, with 156 out of 200 surviving.
Next, obviously, half torp cruisers and half Swiss army cruisers, vs Unshield. Same as prior tests. The results are that the cruisers win, with 124 survivors out of 200 (68 torp and 56 Swiss, not that it matters).
It looks like the best setup to beat the Unshield is probably the Swiss army cruisers, who are incredibly powerful. I'll just quickly test them against some 422BBs and some all-kinetic battleships.
Edit 5: The Swiss army cruisers won against the 422BBs, with 134 survivors. They won against the kinetic battleships too (giga, all kinetic, exact same defence as 422BBs), with (not kidding) 134 survivors.
So, it looks like the Swiss Army knife is a damn good model, although its ability to be enhanced by not being in a monofleet is situational. All around this has been pretty fun and I've learned how to use the console, and how much time it takes to do stuff like this, so I have a lot of respect for the people who've been doing it for ages and do it much more thoroughly.
