Achievements from only playing Vanilla, such as PvP titles. I only got Sergeant because right before they removed the PvP titles, I lost Stone Guard :[

Old School Ride when the achievement system was implemented.
You could mention the Nightmare Drakes ... only vanilla people know what you're talking about. :P (Most vanilla players probably even forgot all about them).

So, anything else apart from PvP FoS, Original epic mounts and BC intro event gear? (and maybe corrupted Ashbringer?)
