Ref: http://www.wowwiki.com/Armor
Against Lv83 the armor cap is suppose to be 49,905. but i am hearing some people say 44k give or take. now if 49.9k is the 75% Damage Reduction (DR) then, 49,905 / 75 = 665.4 armor per 1% against lv 83 mobs. Protector of the Pack gives 12% which if you take 665.4 and multiply by 12 you get 7984.8 armor that protector of the pack reduces it by. so the NEW armor cap should be 41,920.2 armor. where are people getting 44k from?
even if you use against lv80 mobs (45,697) which dividing it by 75 you get 609.29333 armor per 1% against lv80 mobs so protector of the pack's 12% is 7311.52 making the new armor cap 38,385.48... still not even 44k that people are saying it is... false?
