Until you see me hit something with a mace this study is inconclusive. Plus, it doesn't really matter how good your armour is at absorbing impacts, because physics dictates I can still hit you hard enough that you fall over, at which point your face is mine. And main characters don't wear face armour, unless they're Khans.

As a side note Genghis Khan used to lead from the front of his army until he was hit by an arrow, then he lead from the rear center from then on. True story. 

Screw that leading from the from the front and taking your helm off kind of BS.
