The range is the weirdest thing. System Expertise does increase the range by ~50% and nothing else does, but the exact amounts I couldn't pin down. In play, I find the extra range is very impactful and consider omens/shades Sys Ex or bust. It lets them fire completely over allied ships more reliably.
EMP Emitter has a specified range of 500 on its
.system file (
emp.system), which is also listed in the
wiki. Thus, System Expertise would raise the system range to 750.
I do think it makes sense for the EMP Emitter - and other direct-damage ship systems - to benefit from general damage increases like CR and Cyber Aug. Unlike something like Tactical Drills, EWM, or Ballistic Mastery, the "+X% damage dealt" line makes it sound like it should affect all damage dealt by the ship - except, according to the code, it actually does this by boosting only
ballistic/energy/missile damage, which isn't obvious from just reading the skill descriptions.
The interesting thing is that Mine Strike
is affected by missile damage bonuses (or, at the very least, the missile HP bonus from Missile Specialization) and, so, is theoretically boosted by Tactical Drills and Cyber Aug. Yet, EMP Emitter does not appear to get this same treatment at all for energy weapon bonuses. I can only assume this is mainly down to how the ship system is implemented and how damage modifiers are applied. I do know that there are other examples of damage modifiers not applying as expected, like Rift Lightning and possibly the rift explosions from the Rift Beam and Rift Cascade Emitter not being affected by EWM at all, so the EMP Emitter isn't alone in this regard.
