During our most recent guild run of Mag's, the plate DPS helm dropped. Rather than disenchanting it, since nobody wanted to roll on it for off-spec or for alternate gear (which seems a bit of a waste) - we could have the person who gets it donate a VC or the equivalent in cash, or even more than that, in exchange for it.
IE, I pick up a sweet ret helm and donate 2 void crystals to the GBank, or Ekimmu gets a nice replacement for his goggles for when he drops eng for inscription, and then he donates 50g to the bank, or some equivalent.
What do you think?
