I would like to point out several differences between the "Advanced Armors" perk and the rest.
Firstly, scaled and plate armor are not capitalized as are the other armor types. Then again, neither is glass, which is probably a typo.
Secondly, note the perk name itself, which is advanced armors. I assume this to means you unlock the ability to craft enhanced armor types, not unlock the ability to unlock more perks which already have to be unlocked by themselves!
And lastly, the "Advanced Armors" perk lists 2 different names rather than the other perks which only list a single name. This is probably because "scale armor" is an advanced light armor variant and "plate armor" is the advanced heavy.
This seems to suggest that for each material there will be at least 2 different craftable variants, possibly 4. There will be at least 2 for each armor material if, for example, elven is always light armor, and daedric is always heavy, etc. And there will be at least 4 if you can, by default, make a light or heavy armor variant for each material, because the advanced armor perk adds 2 more.
An example of 4 armor variants for steel would be steel chainmail (default smithable light armor), steel scale armor (advanced light armor), steel armor (default heavy armor), and steel plate armor (advanced heavy armor)
However, I think it is more likely that each armor type will have 2 different variations rather than 4.
It was pointed out that the description for the light armor skill is as follows:
Light Armor: Those trained to use Light armor make more effective use of Hide, Leather, Elven, and Glass armors
Meaning that those are exclusively light armor... Thus 2 variations
I'm assuming there are disadvantages to advanced armors to balance out the increase in armor rating; most likely an increase in ore/materials required to craft the armor and a greater weight, which in turn may make these variants more cumbersome.
Do YOU like this new armor system? We lost the greaves slot but have gained at least double armor variations
Oh, and I think I solved the mystery orc pictures that had similar iron armor, but one had plates
