Well to be fair the ZA would be long gone from 74 if it wasn't for their POB being near impossible to kill. They are only about 4-5 members I've read, which is kinda comical to see all this fuss getting made over such a small group of players that's vastly outnumbered by other official factions attacking them.
I think 74 should still be a Zoner Guard system, don't understand what lead to it no longer being one? It even has Guard NPC flying about in it still. And if it was still a Guard system, the ZA would have no right to build POB and blockade the system from other zoners entering.
