For the me, the real and final fix for FW would be including the following:
Two mechanics to "weaken" the NPC sovereignity on a FW star system
1- Complexes
Deadspace Fortifications used by the NPC navies of each empire to serve as staging points for their navy fleets. Two categories only:
Garrison: intended for t1 frigs, faction frigs. NPC rats there are frigs and dessies.
Facility: inteded for t2 frigs, t1 frigs, faction frigs and destroyers. NPC rats there are frigs, dessies and cruisers.
No further sizes or difficulty grades.....just those two, providing newbies and vets a "controlled" fighting enviroment where you can travel all over low-sec with some degree of liberty (speedy stuff is easier to move around and to loose), but also means more sites to be "captured".
2- Missions
Missions from level 1 to level 4 as they currently exist. Each mission not only gives ISK and LP, but also adds a small ammount of Victory Points towards contesting the system on which the system was run.
Capturing systems is through the current Bunker mechanic, with a slight adjustment:
Bunker Hitpoints reduced in half, but a permanent (and constantly respawning) NPC fleet guarding it, this defense fleet has a mix of scrambler frigs, Ewar cruisers, BCs and BSs. Assaulting fleets cannot just "sit and shot", and a small fleet of defenders can choose to side with the rats.
Any outlaw who enters plexes or missions or the vicinity of bunkers will be shooted by NPCs if they don't already have aggro on other targets in the same location.
So in essence:
-PvErs do contribute to the control and dispute of FW systems
-Plexers fight in a more balanced enviroment (no more t1 frigs tanking large installations with multiple BSs), more newbie friendly too
-Bunker busting is a coordinated effort to deal with the NPC fleet defending the site, but requires less time to shoot through its HP ammount.
-Pies are shot by NPC navy
The permanent wardec thingie should remain as is.
