You mean next expac? Since I'm pretty sure its impossible in KA content. I just use the disguise when I want to use the banker there.
I think many have wondered about crusaders of greenmist faction, and the all but useless crafting area of the crusaders cave. Kinda feels like an unfinished idea, as if Domino was gonna have more crafting quests there, then decided against it. I remember her sounding almost like she outdid herself with the crafting quest count as is. I thought she did a miraculous job, and I pray whomever steps in for her in xpac14, can do even half as well, that would be a /win, to me, I think she set the bar really high.
