The biggest future fix would be combining the 4 warzones so that you can fly directly from Gallente space to Amarr, Minmatar, or Caldari space without having to go through highsec or non-FW lowsec. And in restructuring the map so that this can happen, it would be imperative to create multiple entries in to each region’s space so that you don’t get stuck with 24/7 camp that cuts the map in half like on the Pyne/Hikko gate where people just safe up on the citadel at the first sign of danger. There would be also a handful of “no man’s land” systems scattered throughout the warzone that cannot be captured by any faction (they tie into the 3rd fix below).
The second biggest future fix is the creation of a non-capturable strong hold system. Put a non-destructible station; i.e. a faction HQ, at each respective faction’s entry point into the warzone. This system and station cannot be captured as it will act as the fall back point if a faction gets steamrolled out of the warzone. I’d take it a step further and beef up the gate guns for that one specific entry point system’s gate from highsec into lowsec (it doesn’t make sense a faction wouldn’t beef up the defenses to ensure a safe route for it’s fighters to enter the warzone). It’s a great way to get new players into the warzone and its gives everyone a base to regroup and reform after things have gone south.
*The station would ideally be a 1 off (devs only have to create 4) mega station who’s structure represents each factions specific design with beefed up station defenses since it’s an HQ.
The 3rd biggest future fix would be the creation of a FW front line that affects the capture of surrounding systems with a N+1 (can adjust the modifier if 1 is shown to be too constrictive) feature for plexing and capturing systems. For example, system A is owned by Gallente and is connect to systems B and C. Gallente pilots would only be able to capture B and C. Once B is captured, it would unlock all connecting systems to system B to be captured. The front line forces pilots to meet and fight to capture systems. The “no man’s land” systems would provide different access points for each faction to get a foothold elsewhere if efforts are stalling. It forces groups to interact with each other and does away with the army of AFK plexers in back water systems. It also means groups can take a break and roam the warzone again without having to worry about every system burning 24/7
Those 3 fixes are super big projects but would add the most ROI on time spent making it work.
