Praise Pelor, an Armor Epiphany!

[Tequila Sunrise]

Your armor system doesn't appeal to me personally, but that doesn't mean it is bad. To each his own. However, if you have any interest in historical accuracy, you might want to swap the scale and chain. Chain armor was enormously more effective than scale armor in most cases, except when fighting an opponent with a bludgeon such as a mace or club. Scale armor had weaknesses, particularly from piercing attacks, and the scales could be broken off much easier than the links on a chain. Even when the links did break, they often exposed much less than a broken scale did.

Thanks for the tip; unfortunately 100% of my medieval knowledge comes from lame history classes and Le Morte de Artur type literature.
