"Well, the armor would be standalone and use seperate item codes than the vanilla armor on the leveled lists. So that wouldn't be a problem." While that's a fix for the npc problem, it does mean that the armor won't be found in the normal level-lists in game, thus requiring crafting or console commands. Also, as standalone armor, what reason other than balancing is there to make invisible armor for anything but the best armorset ingame? Otherwise it seems to be an alright fix if you need invisible armor. "I wonder how many people actually downgrade to light variants? I use the Conceal Armors mod to completely hide the armor." That’s just like, your opinion, man. But in all seriousness, there are plenty of people, me included, who like and use the lighter armor variants for there visuals. Some people like to mix and match lighter sets and invisible armor together for various reasons, like a piece of cloths clips with some armor, but would like to benefit from the armor values of the heavier sets. In the end though, if all people needed was a simple invisible armor mod, then a simple standalone version makes sense. I doesn't help though that Concealed Armors, while outdated, was very popular and did more, which allows it to get a larger audience.
