Armor HeadGear is a bit different then the rest of your armor.
Most headgear has a bonus of +1 to a single attribute. This “attribute headgear” is available for all attributes, although characters can only obtain attribute headgear for their primary profession’s attributes.
One of the way to manage your builds is to have a different HeadGear for each build.
For example on my warrior I have an axe, sword and hammer builds.
So I have 4 different sets of HeadGear for my builds.
