You can rest easy now!
As the Royal Apothecary Society has found a cure, it was confiremd by Blizzard that the Zombie Infestation will end today.
Scourge Invasion and the necropoleis will still linger on for a while but, zombie players will be gone for good.
Well... I enjoyed it for some time.
First as a Zombie and in the end with my paladin killing them where I could find them.
Curing infected people earned me in 5 minutes more thanks then in the last 3 monthes.
I never really was insulted by doing it. So I guess I was lucky.
