hi in hyjal appear legacy promotion header: scroll of resurrection but its a bit confuse, the correct isnt show this npc https://www.wowhead.com/npc=71304 under vendors header with all items from this old promo instead?
I think that in vasirj the same thing happens

Well, we don't do that for headers that fulfilled a specific purpose. As a compromise, the coordinates for the vendors have been added. You can plot them with TomTom installed by Alt+Right Clicking the header.
