I see what you did with regards to some of the armors that were odd like banded iron and added imperial light armor to matching set. So what is the deal with Studded Imperial Armor and the Imperial Helm?
Looking at the items, Imperial Light Armor, Studded Imperial Armor, and Imperial Armor are considered three different material types( ArmorMaterialImperialLight, ArmorMaterialImperialStudded, and ArmorMaterialImperialHeavy respectively). Imperial Heavy was already part of the Matching Set perk, and it looks like you added Imperial Light, but what about Imperial Studded?
Also, the Imperial Helmet is kind of screwy, its armor type is heavy, yet keywords for perks has it as light armor and its material type as Imperial Studded. Meanwhile the full helm version of the item (ArmorImperialHelmetFull) is set as heavy armor and has the keywords for heavy armor and Imperial Heavy material. This would seem to indicate that the regular helmet (open face) was intended to be light armor and go with the Imperial Studded Armor, while the full helm was to go with the heavy Imperial Armor. Further compounding the issue is that the while only the heavy Imperial Armor set as craftable (via the Steel Crafting perk), the open face helm that seems like it should be a light armor piece is craftable and not the full helm which actually is part of the heavy Imperial Armor set. This is the only instance I can think of where craftable set isn't actually a set.
However, it gets a little odder. When you join the legion you can get either light, medium or heavy armor.
Light uses the leveled list CWPlayerUniformImperialLight, which consists of an Imperial Light Shield and the ArmorImperialLightSet leveled list (light cuirass, light boots, light helm, light gauntlets).
Medium uses the leveled list CWPlayerUniformImperialMedium, which consists of an Imperial Shield and the AmorImperialStuddedSet leveld list (light helm, light guantlets, light boots, and imperial studded cuirass).
Heavy uses the leveled list CWPlayerUniformImperialHeavy, which consists of the an Imperial Shield and the ArmorImperialHeaySet leveled list (heavy cuirass, heavy boots, heavy guantlets, and the open faced helm).
It seems to me that there are two options to bring these into line with the other armor sets:
Option A
- Change the armor type of the open face Imperial Helmet to Light
- Add ArmorMaterialImperialStudded to the light armor Matching Set perk and have the appripriate checks
- Update leveled list ArmorImperialStuddedSet to give the open face helm instead of the light helm
- Update leveled list ArmorImperialHeavySet to give the full helm instead of the open helm
- Update the recipe ArmorImperialHelmet to give the full helm
Option B
- Change the open face helm material to ArmorMaterialImperialHeavy and the keyword to ArmorHeavy
- Figure out where Studded Imperial Armor fits into the Matching Set perk scheme and make the appropriate changes to it
Option B would seem to have the least likely chance of causing problems as it doesn't touch the leveled lists and requires the fewest changes to bring the Imperial Armor sets in line with the others.
