So far it's going decent. I started by getting a tri-tach loan, buying marines and heavy armaments, and raiding chalcedon/epiphany's spaceports. Afterwards sold them a ton of stuff for egregious prices bought from nearby raider bases/free ports. This really jumpstarted my game, and I was able to buy a good fleet after just a few months. Armed with 2 castigators, a XIV eagle, two pirate falcons, 7 mules and some civilian ships I went exploring. Thought I lucked out after I got a fleet log notification of a habitable world orbiting a water world 8 light years away from core worlds. It turned out I was kind of even luckier but kind of not. That system also had another habitable world for a total of 3 habitable worlds in a single system, and also all 3 domain-era system buffs. The bad thing, it was a medium danger system.
I couldn't avoid a fight with two sub-ordos, but found to my surprise that AI is actually quite good at piloting the ships i'd chosen. In fact, my fleet wiped the floor with them. Castigators especially seemed to be really strong against remnants thanks to their ability to chase. I only lost a single mule but cashed in with a few sparks and an alpha core. After exploring the system I went back to cores to prepare for colonization.
Bought an XIV onslaught, another castigator and two condors to prepare for taking the station down. Resupplied and bought lots of crew and supplies to fully colonize the system.
Daydreaming of all the money my new colonies would bring me, I headed back the system without care and happily ignored the warning of hostilities when jumping in the system. I thought I had such a powerful fleet no remnants would be able to fight me. Boy was I wrong.
Next thing I know I'm being swarmed by six, yes SIX, FULL, REGULAR(NOT SUB) ORDOS all with radiants and other capitals from mods. wtf? Was this not a medium danger system? This was the first time I was forced to reload an earlier save.
Turns out beating ordos with only AI is quite hard. I tried two more onslaughts, they got flux locked and just stood there despite being equipped with max vents, flux distributor, needlers, flak cannons and hephaestus cannons. At least they managed to survive for a long time though. Next time I tried two conquests, they got absolutely demolished by radiants pulse lasers, it wasn't even funny. Then I tried a paragon (Was only able to find one from prism freeport, since I'm enemies with tri-tach), this was the best result of all three, but still not enough. The paragon wasn't able to finish off enemies with only 2 tach lances and 2 plasma cannons, but with 4 tach lances it quickly maxed its flux and resulted in the same state as onslaughts. To top it off, enemies seem to be smart enough to avoid the paragon completely and instead focus on my other ships, and once those are down gang on the paragon.
After banging my head against the ordo-wall for 3 hours, I just snuck past them and set up the colonies and left the system. I don't really want to cheese the game by building high commands, and definitely don't want to do this for every medium-high danger system. I must be doing something wrong, surely ordos are beatable without a player flagship doing all the work?
