Antesignani?

[Watchman]

Write that down to being, on the average, bigger and stronger thanks to more balanced and protein-heavy diet and healthy living in the woods. And I guess combative physical sports were pretty common too. *shrug* Hey, I didn't make the rules. I just cross-check the numbers add up like they should.

Also, I rather suggest you take a look at the defense score totals of, say, said Lugoae and similar unarmoured low-and-light troops and compare them to well-equipped and -trained folks like the Reformata and whatnot. The agility bonus - generally not given to anything with armour value over 8, IIRC, except some *really* elite bodyguard types - is there chiefly to allow for the fact IRL even unarmoured troops were actually sorta difficult to kill in hand-to-hand as long as they were fighting back; at least part of which was due to the certain benefits of nimble and unencumbered movements. (Properly designed armour doesn't restrict you much, but it *is* more or less heavy and depending on the design disallows a variety of posture shifts and whatnot.) Particularly the open-order types with room to maneuver.
Compensation, essentially, to fudge the system in order to get the desired results. I'll remind you it's not like the levies and whatnot stood much chance in a straight fight with quality troops regardless...
