I found none of the new HQ items on live. There should be five of them. Considering this is the Heritage Quest server, I'm hoping this was an oversight and will be fixed with the next patch.
Looks like the items just haven't been created on Live, or if they have, not added to the NPC who sells them.
Nothing has been done to add these to the merchant on TLE as well. The only thing that has happened was the expansion being turned on unfortunately.
I'll let you know if I ever finish it. Been trying for five days to get into Halls of the Forgotten for an update, to no avail.
Are you the person who has been asking for an empty instance of Halls of the Forgotten? Mayhaps you could just form a group to go clear it?
