:et's think about this rationally for a moment....
You can only access the glamor plates in certain areas due to legacy code restrictions (I think that's the reason anyway).
In order to automagically display the true nature of the item to some or the glamoured version to others some new code is going to have to perform a check for each character in visible range and on the fly display one or another version of their gear.
Any idea how many hours of dev time that is going to take away from actual development? I doubt it's even actually possible simply due to the spaghetti legacy code.
