Without the nav beacon method of undermining, there is almost no way to fight Cutter haulers hauling thousands of merits / hr.Nav beacon manipulation to force spawn ships is an exploit & you shouldn't be doing it as you are not playing the game as intended and the NPC's that spawn also aren't more challenging than those in Strike Zones unless you find Sidewinders & T9 tricky which I doubt. Also you can't use AFK turret boats with the new CZs afaik as the CZ times out & you have to re-select the faction. And, finally, one would hope that new Powerplay CZ's would have a balance pass to provide a suitable challenge or FDev uses feedback to tune it.
You refer to nav beacon manipulation as farming which I think pretty much gives the game away to why you want to keep it.

When Frontier reworks conflict zones that constantly spawns targets at 30 merits per kill, talk to me again about the nav beacon spawns being removed for Powerplay.
