Nostalrius Begins - Quality wow vanilla realm (1.12)

I played retail classic on Talnivarr-EU (PvP) server. When it came to Kazzak, horde and alliance guilds would gather in a safe distance and take turns on the boss. If one guild failed to kill him, the next one gave it a try. There was only some griefing when Kazzak was first introduced. Later people realised it's just a colossal waste of time and whoever got there 1st with his guild got the try. If they failed, the next guild gave it a go and so on. Back then we didn't have the 1.12 talents and not everyone in BiS gear, so a kill was never guaranteed.
