This is not made by me but it is one of the greatest moments in World of Warcraft where some brave individuals managed to do the … all » unthinkeable. All credits go to the makers of this video.
World of Warcraft Lord Kazzak is lured into Stormwind by the enemies and destroys Stormwind within 1.5 hours. After this event the server is resetted and a rollback was performed by Blizzard.
Lord Lazzak must be killed within 3 minutes or else it will turn into an invincible monster. For every kill it will get so many HP that it can't be beaten by anyone. Luring him into Stormwind, basically destoryed Stormwind.
