Here's some comparisons between Samurai armors and others (prot, def, enc, res):

Samurai Armor: 14; -2; 3; 10
Full Scale Mail: 14; -3; 3; 12

Heavy Samurai Armor: 17; -3; 4; 14
Plate Hauberk: 17; -3; 4; 20

Kabuto (Helmet): 16; 0; 0; 6
Half Helmet: 17; 0; 0; 3

The helmet takes way too many resources, but
the basic Samurai armor is actually resource-cheap, and Samurai Armor allows mapmove 2 (unlike Full Scale).

Just lower Kabuto cost to 3, and Samurai Archers are 23, Samurai without bows 18 and 20 resources, Samurai in heavy armor 23.
