You should be getting more. EDENCOM battleships and Drifters should be giving you 0.05 or more per tick. Also, once you get to 1.0, you can ping between two border systems to increase the speed.
But yes, getting to 3.0 will take time. Not the insane amount as on release, but still at least 10 or maybe 20 hours of play I guess. I’m not sure Rogue Drones are even worth it, other than perhaps to get quickly positive with both EDENCOM and the Trigs. They do say more combat anomalies are coming, so maybe that will decrease the waiting time, but it isn’t going to make this trivial.
