Hi All,
This is a noob question but I haven't worked it out from ESO wikia pages and the like. How does the armor rating system work in ESO?? Does each item add its own value and the sum total is mathematically related to the damage you take in combat? Is there a cap beyond which is useless to improve your armor? Can you check your total armor rating value?
I remember in Skyrim, the cap was something like 547 and it was the same for Heavy or Light armor, so you could easily reach it with light and the advantage (besides not looking like a tank:) was you get much more inventory space because light weighs less than heavy. That seems to not matter in ESO, since they're all treated as single items regardless of weight.
I just left Auridon, so still close to the beginning of the game, but for now it seems Heavy armor is a better choice, you survive longer. I've seen passive abilities that come with each armor and it comes down whether you want more health, stamina or magicka, so totally personal choice. I use up stamina abilities first when in combat but that all can change when I get to better abilities.
