I was ecstatic. This was all I could have hoped for; a near-total break down of day to day life; chaos in the streets; the infected fleeing their homes, hoping for a cure elsewhere and only succeeding in spreading the plague further. I picked up the infection easily enough and spent an hour or two doing my part for the Lich King.
Maybe, as Mike suggests on WoW Insider, the escalating infection rate and vectors of the Plague were designed by Blizzard to take advantage of emergent gameplay in World of Warcraft – certainly some people were encouraging others to get infected and spread the joy to others. I saw more than one player claim in the Trade channel to have infected one or another faction leader.
"One lasting memory of the event I have read simply, "Stay out of Stormwind, it's infected.""
Some of the spoilers leaked recently hint at big things to come in the next few days. I certainly hope so, because I would have been interested to see just how bad things would have become, had the infection spread for a just another day or two. I've managed to avoid said spoilers thus far, so forgive me if I'm off the mark.
I realise that what I'm suggesting is probably going to be quite unpopular. People log into WoW for fun, and exactly how much fun can be had when your usual tasks are impossible? Can you still enjoy WoW when your home city is crawling with the Undead, or you can't keep up with your Auction House trading because all the Auctioneers are dead? I know I could, and indeed can, but I feel pretty sure others will feel differently – hit the comments and let us know.
