The main purpose of this question is to be able to enter a series of armor values for gear, and then calculate a value that exactly matches the character paper-doll screen and the armory value for any given character.
The answer must take into account character level, bonuses from gear, enchantress buffs, and strength. For the armory value, what buffs apply? I believe if Warcry is spec'd, then on the armory page, it does factor into the shown value.
Currently, the equation I'm using is:
Armor Value = Armor Values on Gear + Strength However, this is calculated value 39 armor lower than the in-game value. The disparity is even greater when viewing my character profile, which has Warcry spec'd, even accounting for 20% increase in armor.
