I value head armor more than body armor. Familiar with overheads and the left to right swing, especially from the one-handers? Headhunters! Without a helmet you're down in one shot, maybe two if you're lucky. Also, arrows doesn't always one-hit kill in the head, heck, even crossbows doesn't. Just yesterday, some guy survived a headshot from MW Arbalest + Well made steel bolts at short to medium range with a good helmet.
I don't care too much about the price and possible changes to that, I just find it strange that people don't value head armor.
