I see all of your points, but I now have a point of my own thanks to a first hand experience at the most bullshit thing I've seen and heard in all my time in the server.
It was the third judgement waiver in what felt like an hour or less. There was a huge rebel holdout in the top floor of the slums apartment, mostly mp7s and spas-12s I wanna say, (I didn't see the weapons but I heard them) OTA vests helmets, I heard they had combat gasmasks too when a grid threw teargas, and they had a purple Vortigaunt which gives them wallhacks to see combine.
But the stupidest (or at least the strangest) thing I've ever had to witness, was that they literally had damn near infinite ammo, because they were using their stash box in the apartment to take out more boxes of their stashed ammo. OTA and CPs were either dying, or running out of ammo and needed to retreat, while they stayed cozy in their apartment that has a ladder choke point for 20+ minutes. this is the perfect example of what I'm talking about, but it involves an entirely different part of the issue which, I didn't even know was possible or allowed, because this is the first time I saw it.
So screw an ammo box limit, make every stash box in the city have the same properties as the ones out in the 404 zones, either not accessible at all during JW, or at least make it so you can't take anything out of them until its over.
