On top of that, they always seem to turn their flank to the core of enemy fleet to shoot some frigate...
Hmm - do you happen to have a save handy where I can directly observe the behaviors you're describing? That'd be very helpful.
It's nice that you are reading feedback.
Unfortunately, no. It may have been a slight exaggeration, but I can be a bit more specific. I've observed this sort of behavior a few times. I had a smaller fleet of bigger ships (2-3 capitals and cruisers) vs big enemy fleets of close to 30 ships. I group all my ships together and wait for the enemy blob to come. What happened fairly often is 2 capitals would fight the blob, sometimes the third one too, but instead of shooting into the blob, they would try to shoot single ships that split off from it to flank, usually smaller ships, but sometimes bigger ones. The issue is that it enabled the blobs to concentrate fire onto the capitals, while taking no return fire, as they're facing the other way, which is naturally way worse than a single ship trying to flank. All of the officers were steady. But yeah, essentially, the entire fight they would face away from the main force and try to very slowly pick off separating ships.
Even more specific information if you want to try and recreate the fight:
Spoiler
400 battle size, had to cap 2 points to deploy all that.
My fleet: 1 paragon with 2 tach lances and 2 autopulses, 2 14th onslaughts, 2 auroras, an SO harbinger. Auroras escort onslaughts. Steady lvl5-6 officers.
Enemy fleet: 2 guardians, about 14 ramparts, 13 smaller drone ships. 2-5 dmods and red officers in each. (a rare bounty, I assume).
Maybe I deployed them wrong, but pretty much always the auroras would sit behind the ships they're guardiang, doing seemingly nothing. One of the onslaughts would also remain behind between the 2 other capitals, seemingly not even trying to engage.
