But it is perfectly okay they ninja our stuff?
/shrug Not a perfect system.
I know of a couple Warlocks and Mages that went ahead and got Shadowmourne, yes. During Wrath, while their guild was still clearing out ICC. One of the mages was the first in her guild to have shadowmourne.... really bugged me...
As far as I know, it only needed to be in their bags.
Last I checked, the only ones who could start the quest chain for Shadow's Edge were warriors, death knights and paladins. Did I miss them changing that?
