After watching some combat logs with regular NPC's in missions i noticed that NPC tend to do weird damage values to each other with torpedoes, and it ranges from 10k, which is ok i guess, to something like 30k, and that's crazy. My own pets do 20k dmg with torps and both enemies and friendly NPC do same to each other. What's that? Doesn't look like regular attack. Especially if that stuff hits my hull, and that means more than half of my hp gone...
Also i took screenshots, but there isn't any interface elements on them, so those screens are useless...
Update: Well, it seems that i have solved this problem. It was a weird difficulty bug, that caused damage done by NPC multiplied even more than with elite difficulty. I had to switch to elite, do some testing, and then switch back to normal, and it worked! Now torpedo salvos does not crit me for 15- 20k, just a mere 4-6k, and beams and cannons got normalized as well.
