Right, so Harris, Compa, and Gina take care of two noobies, and as a reward… They get to keep all the loot? So there's no fucking incentive for them to take care of them, is there? Imagine working somewhere, and your boss tells you that from now on, you're going to have to train new employees, but not to worry since you won't have to split your wage with them. The fuck? Yeah, sure, they could do some work, but let's be real, you'd have to double-check everything they do anyway—it's a net loss for you. “Stable income” my ass, it would be far easier without taking care of two rookies. They're just playing babysitters for free.
As I stated in my comment last chapter, the minimum requirement on the amount of people in the party doesn't make sense if they can just fill it with rookies. At this point, they could pay two homeless people a silver coin to become their “party members”.
