No, idea how it works for the NPCs Chars. Probably at full if you have only one PC. Seems a bit to strong for being compensation for No-Bless/Curse, or whatever the reason ist. Solo-campaign with 4 one-man-army sounds extremely easy. I think NPCs would need harder limitation to make one-man-army really required.
Honestly I would prefer it to be the estimated solo-run trait like lonewolf, if you take it, you can't take NPCs and you can take it from start.
