One integral part of World of Warcraft back in the day was powerlevelling: I remember a starry-eyed Harvey watching Protection Paladins on YouTube sweeping through hordes of the Scarlet Crusade for a group of lucky levellers. I was completely unaware of the economic underbelly supporting it, but it sure looked cool to see someone soloing a dungeon.
It was doubly helpful because levelling back then was a bit of a pain. Even without any fancy tricks in retail, levelling up an alt account today doesn't take much time—but back in the Burning Crusade? It was a journey. It also helped you rake in gold as a nice bonus, something that was also in more meaningfully short supply.
