I'll be adding a short delay to regeneration upon taking armor damage in the next version and the Dominator specifically will lose 100 points of armor. That, however, is the most I'm willing to nerf the Daemon defenses at this point as they are intended to require good ship builds, fleet compositions and some player skill to fight effectively. And yes, they have somewhat comparable armor to Remnant, but they also have generally worse shields with worse coverage.
I do want the Daemons to be a challenge, but it's a complicated scenario. The changes you mention won't do much because the primary issues are the agility, the hull tanking, and the fast repair time. I've seen Hel Dominators recover from a flameout before I could actually respond to the situation. Like under ten seconds. It is almost pointless to try EMPing Daemons.
I don't think many people get how the balance works, because shield efficiency doesn't determine how good a ship is at tanking with its shields, it's the ability to withdraw and vent. All the daemons are more than fast enough for this. The only ships break this trend are the ones that cheat like the Paragon and Monitor. They benefit greatly from increased efficiency.
But the Daemons do have an extra advantage in that they typically run ballistics and missiles, which typically have greater range than energy. So they
act faster, even if they don't have the raw speed of Remnant ships.
As much as I like the Hel Carapace as a concept, it actually accentuated the strengths of Daemon ships. It might be some magic combination of elite Combat Endurance and Damage Control, but the hull tanking of these ships is ridiculous. Both the higher base armor damage reduction of Hel Carapace and the ability to withdraw at any time to repair armor made them more survivable.
The problems I have with the Daemon series are largely why I find the Remnants a bit ridiculous : you can't pin them down. My best suggestion would be increasing repair times for flameouts and possibly reducing hull.
Oh yah, and here's a mod list :
