I saw this image on the pcgamer article:
TW said on their main page when the two videos were released "Their behavior is drawn from actual historical tacticians, for example Alexander the great" when talking about key battle improvements. So they are using historic things to enrich the game. But now look at this picture. I'm seriously doubting the historic accuracy and the efficiency of these armours. Metal points on leather armours? And look at that golden helmet... are you serious?
I'm no expert but I'm sure there's a lot of innacuracy on that image. And we should also be aware of the time period of the game.
