I noticed that. Luring to many enemies into the militia is shooting yourself in the foot in the long term. I don’t think it should be changed, however, except for notably smart and strategic enemy groups. Why would undead or orc warriors bent on glory care if a dozen more “fleshbags” get in their way? Luring could work differently for bandits, for example. Maybe for werewolves, but even there I think “bloodlust” is a valid explanation of why they won’t stop their hour-long pursuit only because a few caravan hands showed up.
Regarding save-scumming, I am strongly in favour of implementing an optional Ironman mode. It shouldn’t be forced on anyone, but it would be great if those as weak-willed as me could have it to limit themselves. I don’t think it makes much sense at this point of development, however, since it would very much impede bug-hunting and balance testing.
