I'm on something of a simplification obsession at the moment and Armour Rating has come under scruntiny. Currently, for PCs there is an armour rating for each part of the body. I know why I did this - so you could have a heavily armoured helmet and less body etc. For a stock human, AR is just 1 all over.
However, while creating the armour section for the next version of the equipment index, I really don't think it adds very much. I am beginning to think that an armour has a single armour rating. Also, it's telling that over the years it's not really been used very much and we've certainly playtested the hell out of it!
What do you think?
