Yeah but I had 3:1 odds... as in I had 60 or so and they had 20.
If I had 60 fresh recruits, against 20 looters, I'd expect 3 dead, and an equal number of wounded - with my damage settings set to regular. Against mountain bandits, double that, and against sea raiders, double that again - in other words, 20 sea raiders should kill at least a dozen untrained raw recruits, minimum, even at 3-1.
But diversify your band beyond the first chevron? All of those numbers should drop. 20 cav, 20 melee, 20 archers? And 4 of those cav are your heavily armed and armored lieutenants? Even the sea raiders should be hard pressed to even wound before being obliterated. Flip it around - I ran into an enemy mercenary company that was entirely cavalry - though I outnumbered them by 2-1, almost half my troops were still green, and they broke from the first charge without so much as a single kill . I think I reduced the enemy numbers by maybe 10 before loosing entirely.
And functionally, what the cyberninja looter mechanic does is not only force me to fight in person, but to cherry pick - I'll ignore these dozen or so looter bands because while they total 100 guys, none of them have more than 10-15 members in a given band. It's not worth my time to FPS ten guys if I have 60, or 100, but I wont atocalc because I'll be damned if I loose 2 guys every time I fight 10 looters. If, as a player, I'm just ignoring them, what's the point of them being there at all, and what's the point of autocalc if I never use it unless I'm severely wounded, and have no other choice?
