I really think that they should also add in a "sanity" system. In real life if someone who was a peasant saw a man in full black armor he'd probably flee in absolute horror. Anyone who isn't in at least 15 pounds of armor should have a rapidly rising meter the closer they are to a plate wearer, and when this gauge is full it should cause them to randomly drop an item and flee in terror.
No true, the English have always had a reputation for pure insanity.
http://en.wikipedia.org/wiki/Battle_of_Agincourt The bulk of the English army wear in mail and padded leather. The french were tooled up to an extreme degree.
A man wearing so much armour he can bearly move will be over whelmed and killed by a small group of faster padded nobbers.
The upkeep on any form of heraldic or plate would have to be very high, 10k per round. Then it would be realistic. Most of us peasants would have a snow balls chance in hell of being able to aford heavy plate and its upkeep.
