The thorakitai unit has these stats: armour 12, training 6, shield 4. The principes unit has these stats: armour 13 (with one grave less), training 10 and shield 4. They perform similar tasks in the battlefield. Historically the two units had clashed once (afaik): in the battle of Corinthos, 146 BC. The thorakitai crashed the opposite roman forces but they were surrounded eventually by the numerically superior roman forces. So my guess is that the thorakitai should be at least identical with the principes, if not slightly stronger.
I propose that the stats should be changed to: Armour 13, training 10 or 11, shiled 4.
Any thoughts?

P.S. Happy new year!
