I don’t want asset safety to be player-driven at all - I think that goes against the nature of asset safety and should be avoided at all costs. I outlined some bare minimums to approach making it not totally game breaking, but I still will not advocate for it.
If it were just a fuel siphon without direct impact to asset safety (only hastening fuel consumption to try and move a structure into low-power mode), even then I would say it needs alerts to the station owner that such a device was deployed against them and is spooling up (the low power warnings will alert any players with assets who want to yank their assets after it hits that stage). And probably would need to be ‘manned’ like station guns in order to keep running, though that won’t add a lot of investment - someone could fly to it in a shuttle or a pod to operate it with a clean clone, so their risk profile is still minimal. There also needs to be a way to determine how much fuel a structure has on-hand to determine if it is worth trying to deplete, and a maximum ‘theft’ rate (not a % of fuel, but a hard m3 per second or whatever).
And you still don’t really have any ‘risk’ for deploying it, beyond expense of the unit itself.
