in the Q&A a blue said
"For event items like the Scourge Invasion or the Vengeful PvP set, can we get those for transmog account-wide?"
"We want to make sure that all the times you remember from the good old days are available for transmog. Im happy you brought up the vengeful set, and in Area 52 there are vendors where can you buy these items. Regarding accountwide event items we have to watch out on our side as its kind of resource expensive. We could certainly look into that."
but ive been to area 52 to try to find any vengeful gear.. and theres definitely not any vendor selling it there.. not with any marks or anything. so what are they talking about...
