I'm aware that it isn't likely we will get any of these but if we get loud enough we may see them added.
Also for those who say it would take too much dev time may i remind you that most of these items are still being used in their old forms by npcs, they still exist in game.
White knight armor
Helm of Netiznot
Dragon med helm
Metal chain bodies
Wizard robes plus the trimmed versions
All weapons from bronze to dragon (i miss my dragon hatchet)
lastly old castle wars armor, you know the sets, the red and blue, white and blue, the classic sets.
