I felt similarly in my first playthrough on this patch, but now that I'm on to the second I think I've adapted. The issue for me is not that it's too hard necessarily but more that you are pidgeon holed into a handful of op strats.
And now the game is pigeonholed into abusing frigates with absolutely cracked officers. Whole skill tree showering you with bonuses for choosing to play smaller ships and nullifying all shortcomings of this playstyle. All the while actively punishing you for choosing bigger ships:
You want to use your range advantage? Sorry bud, all fleets now have 40-70% ECM rating that you can't counter without spamming frigates.
You want to make use of your thicker armor and more powerful shield? Sorry bud, now everything deals +40% dmg to you just because you're enjoying the game wrong.
You want to use your flight decks? Sorry bud, fighters/interceptors are utter garbage against small ships but bombers were not affected, so you can enjoy torpedo barrages from all sides.
You want to make your projectiles faster to have at least a chance to hit something more mobile than station? Sorry bud, you need to choose between essential armor skill and this one.
You want to get some dmg bonuses? Sorry bud, all dmg bonuses now work on big ships only.
You want to use energy mastery? Sorry bud, it's working only at point blank range.
Also remember those control points on a map? Sorry bud, but you either taking them with frigates or fighting enemy fleet while grossly outnumbered.
Officered frigates spam turned into fighters spam 2.0 but worse. With fighters spam player didn't got much experience of being on receiving end of it, vanilla fleets almost never used fighter heavy fleets. But with frigates? Every single one enemy fleet have dozens of them. I missed a moment when the game turned into competitive multiplayer where if you don't follow meta you need to try
really hard and be very effective.
In 0.9.1a I used a fleet of single capital + cruisers + occasional destroyers and frigates with 4 decks total. So I have not used capitals spam strategy nor fighters spam. And I still was able to beat any content available. Now I get steamrolled by a single Ordo with no Radiants and after a week of adjusting my fleet I don't see any way to effectively enjoy the game without turning into frigates or turning my cruisers into sudo-frigates by baking SO in them.
Anyway I'm officially moving my residence to salt mines and probably take a couple of weeks off from the game. Maybe there's be a patch of some sort or a mod to make the game enjoyable again.
