DISCLAMER: THIS IS STILL UNDER DEVELOPMENT!
The latest version of this aura seems to be getting there. I had to create multiple auras in the group to track each vulnerability type, and also add the blades and swords additional aura to also show on the nameplates.
I recommend deleting the old group and children, before importing the latest version! It's very important that the child auras are names ends with the spell ID of the thing it is tracking.
In short; this simply adds the vulnerability of the adds during Argus Normal and Heroic, for us BigWigs users. I recognized the lack of this when I swapped over from Deadly Boss Mods.
