I’m sorry, Daggershoot, I checked the one WoW license that is old enough to have been around when that achievement was available, which is an EU license mind you, and I cannot verify that it earned it.
I looked through the multiple tickets you submitted over the last two months and I am unable to locate the Druid or the Death Knight that you mentioned. You have a Blood Elf Paladin of that same name, on your named WoW license on this Battle.net account, but you already found that one.
That isn’t exactly what that does. So no, it would not show you old names or information that you seem to be looking for.
You seem to be under the impression that we just haven’t looked hard enough, Daggershoot, and that simply isn’t the case. The items, characters and achievements that you mention are not available on any of the WoW licenses on this Battle.net account.
Where exactly did we tell you that, Daggershoot?
Can you quote that part of the response you received? The last response I see is a generic one that simply says that our queues are busy and for help with achievements you can check various sources, such as Wowhead or Icy-Veins or ask the community on the forums.
