I attempted to determine what makes the deadliest glass cannon combat build. I started as a stealth build, got myself 5 advanced hacking suites and a system shield, and got to work. I didn't manage to fab as much as I wanted, but I still got the gist of it. The fundamental of the build is two heavy flak cannons, plus a lot of target analyzers to pump up the crit rate, and some targetting computers to hit more. The flaks deliver 6 projectiles each, and the target analyzers bring the crit rate north of 50%. The odds of one of the 12 projectiles critting the core are high.
While it's not a sustainable build (you can't replace the flaks), it works rather well against normal robots. It fails completely against behemoths and special robots. I got stripped against Alpha 8, even though I had the last word. When Kyzrati says Behemoths and co are immune to crits, he means it. It wouldn't be so bad if only the core was immune to crits, but all their equipment is too.
I noticed experimentally that weapon cyclers perform even better than you'd think. Whether you pick the advanced version or the experimental version does not matter. You hit the 50% cap anyway. Rather amazingly, a second cycler has
increasing returns. The firepower increases are respectively 33% and 100%. In practice it works even better because you can get 2 volleys out by the time the enemy gets one.
I'll try pumping core analyzers next. If you get >50% proccing odds, it should work pretty well against all enemies combined with big guns and weapon cyclers.
