I did rank 1 -->5 progression in one "full immersion 8 hours" day of killing stuff, so no expenses (excluding some refill/repair) and 50 Millions insoming next week.
Anyway this way it is a painful grinding, honestly i wont do that again, not worth the effort for a game
Yeah the initial 10K grind is pretty painful.
Just got back from a HazRES and i made 7.5 million in 30 minutes so the pain is definitely worth it in the long run
