Can anyone confirm how orange gear gets its armor value?
From what I can tell it appears to be derived not just from the armor rating but also from the intrinsic armor "class" of the gear. For instance, since the Elegant Dress is a "light" armor class (requires light armor proficiency to use), it seems that for any given armor rating you mod it to, the armor value is the same as what you would see on a light armor chest piece of equal rating. This is substantially less than the armor you see at the same rating on a medium or heavy piece.
I just want to make sure this is accurate, since it seems to unfortunately limit the custom armor options for a heavy armor using class -- no tanking in an Elegant Dress for me I guess
