It’s easy to make Nimble fighters able to avoid 1-shot death from orcs, though. Give ’em heavy armor.
In my current game, I have 3 different nimble fighters. Each is wearing Scale Armor. One was hit by an adult orc with a single-handed axe. He wasn’t even fazed.
Scale Armor + Full Helm + Swordmaster = high in all defenses, really good armor, and with the right perks you never run out of fatigue.
