You probably lost armor due to the removal of armor as a major stat on chest, pads, pack and holster for 1.6. Pre-1.6 people tried to hit 50-55% for damage mitigation from armor and with the 1.6 changes that's dropped about 20% to 30-35% for desired mitigation.I was running at about 11,600 armor. I`ve lost almost 4000 armor in the last month. How do I rectify this?
