Just trying to pull this discussion out of the expansion mission paywall thread.
So, the Darkfang shield: Personally I think it should stay rare. Other than looking different and having no alchemy line, it doesn't have any properties that meaningfully differentiate it from the already common-as-dirt Wise Owlite Shield.
I agree with it staying rare, though I enviously want one, its because they are so rare and why I hunt clockworks daily for em. Its like the scissor blades. A merely reskinned collectors item. It whats make MMO's go round. Rare items.
