My few observations, in no particular order: NPCs are engineered and use experimental effects. I went to a HazRes in a shieldless hulltank and was scrambled all of the time (thrusters and power plant). Interestingly some NPCs seem to use mirrored armour as they take next to no hull damage from lasers, even with corrosive shell added. The one issue I find annoying is that NPCs completely ignore module damage. They are always happy to wake out easily with the FSD at 2% integrity. My FSD starts coughing already around 80%. And concerning module damage I've got the impression that at least in PvE penetrator rails and HYS cannons are still and/or once again borked. Their module damage is nothing to write home about, every PA does more module and plain hull damage, not to mention gimballed multi cannons.
