Next wipe we can have 10 slaves, and 5 human/1-2mutant mercs. And I'm hoping animal followers also have their own seperate value.
So, you can go slaving with your mercs, having them knockout rather then kill.
Example: I go out with 5 mercs with clubs. I enter rave party encounter, I attack and let mercs do work. Enslave 5, take to tent, drop off, repeat till 10. Rinse, repeat. Because followers only are 1 ch to carry on worldmap.
