Oh man, the memories. My server was big on open world PvP, and I was in a large guild that enjoyed raiding Stormwind. We would often storm the city and hold the throne room with a few hundred players. If you got enough Alliance players to stay and fight you, eventually the entire zone would lag, and then the entire continent would crash for about 10 minutes. Any player on the Eastern Kingdoms would get booted back to the character select screen.<p>There is a legendary weapon (Thunderfury) that can only be gained through a long questline ending with an open-world boss fight that takes 20-40 players (depending on your skill level), just for a single person to get the weapon.<p>We raided Darnassus at the same time we knew our rival guild was attempting the quest and successfully prevented them from getting it by crashing all of Kalimdor* :)<p>&gt; Another funny accidental apocalypse in early WoW was kiting raid bosses to cities, letting them wreak havoc until a GM despawns them<p>Blizzard repeated this event as a promo for the BC expansion too! &quot;High Lord Kruul&quot; would spawn in front of player cities with an army of burning legion mobs. He had nearly identical stats and skills as Kazzak.<p>* They tried again next week and got the weapon...
