So the realm Sulfuras still has everything - and I mean everything - from the pre WOTLK invasion event. The areas under invasion have the mobs still dropping stuff like gear, haunted mementos, and currency for the Argent people. We have the necropolis floating everywhere. The argent vendor in major cities. Mobs outside major cities.
I know this was supposed to be removed, and I thought this was a bug for all realms. But some friends came over from Grobbulus to level fresh toons as a time killer and were very confused.
