I am 75% sure without even clicking on it that that link is Pentagon Wars and the Bradley.
Pentagon Wars was actually the second choice, but Fort Squidward sums up the thought process behind my particular case of Bradley Syndrome. I never know what to prepare for, so I try to prepare for everything, overdo it, and then get bodied by something simple I completely overlooked.
I would recommend a more focused array of weapons (meaning fewer weapon types), so that your ship has ONE preferred engagement range and sticks at that range, instead of needing to close to get the microwave in range while for most of your weapons would be effective at a longer and thus safer range.
My engagement range is pretty uniform, everything except the missiles is keyed to 120,000 km, even the microwave thanks to some splurging with starting tech points. The lasers technically reach 160,000, but I remembered that the damage drops off towards the end and I designed the fire control with that in mind. The missiles I was planning to use at the start have a range of just over 18m km. The plan was to open with missiles, close to gun range, pummel the enemy until their shields pop, and then either disable the enemy with the microwave or just finish it off.
Basically, have a laser ship with some point defense, and/or have a microwave ship (with PD), have a missile ship (with PD or AMMs, either way), and so on; don't have one do-it-all ship that can't do anything nearly as effectively as a more focused ship could.
Sounds like my best choice would be to rip off the design philosophy behind Stellaris's corvettes. I could go with four laser turrets, drop the railgun and microwave, and give the missiles to a dedicated ship. Missile boat hangs back and throws rocks while the laser ship runs in to deal damage and intercept missiles, preferably with its guns.
My biggest problem at the moment is jump squadron size. I wasted my starting tech points on other stuff so I'm stuck with with small fleet sizes for... awhile, not sure how long since
for some reason I can't resize the completion date bracket in the research screen. I agree do-everything ships are a slippery slope, but I also need to get the most bang for my buck out of what little I can send out at the moment. strike craft sound good on paper, but the phrase 'low-tech fighter' keeps auto-translating into meat grinder for some reason.
