…The only difference in balance and variety between PvP and PvE focused setups is due to the fact that NPCs suck which means virtually anything and everything works against them. …
And the reason (in my opinion) why NPCs are the way they are is because the game (in my opinion) is based on PvE MMO game concepts as gear progression and "character level" threat.
Giving NPCs the same ships as high end PvP players in the current state of the game is the perfect recipe for disaster (in my opinion).
Oh, I'm all for a spectrum of NPC ability. I simply feel the upper end of that spectrum should give even the most skilled CMDRs a run for their money.
While I agree that there should be NPCs that are a threat to even the most skilled players, but implementing such NPCs would require almost a complete redesign and re-balance of the entire game.
Starting with ship balance (size, speed, defense, offense) and engineering (boost, special effects). All the way down to a redesign of the NPC spawn system would be required (not connecting NPC rank to player rank for random NPC encounters).
And finally there is the problem of player skill distribution and what makes a game fun for players. Finding the balance between challenge and frustration - a balance that is different for every player.
While such changes could result in a much more engaging and fun game for everybody, I don't think FDev can do it in this late stage of the game.
If FDev is willing to make the required (in my opinion) changes, then I assume the change would take years.
