Whatever it will be in the end, I wholeheartedly hope it's not that nonsense. In these times it would be a horrible and totally ignorant signal to encourage to keep thousands of PCs online 24-7.
This is my problem. When I read people fitting a giant fuel tank and flying in system overnight to lower notoriety (2 hours for -1 point) I just see what a lot of people will do to get Arx. If anything, Arx should be gained as you gain credits- maybe 1 million made in game = 1 Arx. You can't tie Arx to some activities (like Powerplay) because that screws incentives, and you can't earn it directly as an option because of RNG.
I really want more detail from FD because this is a minefield if done wrong.
