Not sure if its been posted already, but imagine if the 'Taken' were actually dead, or lost Guardians, Awoken/Humans/Exo? Basically a tougher fight each time we fought these mobs, maybe even a boss fight, they have supers, maybe they could even be the crafters of Exotic gear who died/disappeared/went cray cray. Such a Thorn. (A troll for the Thorn-haters). So a Shadow-Link type enemy Guardian. Ideas to expand would be cool for the imagination!
