As far as I am aware none exist, because in part there is no need due to the AFK boats. As far as cheating in a new CZ, if you have one shot kills mods, you could mercilessly spank any while hoovering up credits from massacre missions. Remember war bonds don't have a pronounced effect on the outcome, so if you can rack up wins alone you have won (so trips back and forward are not required).
Sure, but were we not talking about bots and automating the process. Sure, you can make it quicker and less effort, but the question is, could you fire it up, walk away, return hours later, and it would be beavering away? Or do you have to sit by the comp, periodically alt-tabbing and issuing instructions?
The difference would be between someone being able to do it for hours or someone being able to leave it running 24/7.
