As the title says, for the Pre-Cataclysm, what do you think it will be?
For Burning Crusade, we got a invasion of Demons from the Darkportal, and a Pit Lord at the entrance of every city to kill.
For Wrath of the Lich King, we got a entirely player controlled event. A Plaque that would turn players and most NPC's into Zombies. Along with the invasion of Necropolises.
For Cataclysm, the event has to be just as epic as the events it follows. What, in you imagining will the Pre-Expansion Event be?
Edit: Funniest Type-o ever.
