When the disease grew potent enough to transform anyone it infected within a minute, it became practically impossible to accomplish anything. Especially not with Argent Healers calling for a hasty retreat. Entire cities -- or key areas of cities -- were quickly transformed into ghoulish carnivals and it was simply too bothersome to do any business. As a result, players couldn't put anything up on the Auction House nor could anyone buy anything, either, slowing commerce to a crawl. My wife's daily Auction House profits of upwards 500 Gold dwindled down to nary a copper with her alt being unable to collect from the mailbox, move stuff from the bank, or scan the Auction House, as she died istantly to roving zombies.
What's next in store for us? Did Blizzard really cave in to the demands of players who felt that the World Event disrupted their normal routine too much? Or is there something more devious waiting in the wings? I know my wife was so upset by being unable to conduct her business that she decided to hold off from logging in at least until the event died down. Now that the zombie infestation seems to be under control, perhaps business will pick up again. Or maybe not, depending on what Blizzard has prepared for Azeroth. One thing's for sure, these Dawn of the Dead-type events certainly take a bite out of the economy.
