Aww I'm sad I missed those times! I only joined in TBC, which is where I started pretty hardcore raiding to climb up to one of the server's best guilds. In WotLK I switched over to horde though and joined a guild filled with awesome people, so I had my best raiding times during that particular expansion. After that, I simply didn't have the time for serious raiding anymore, so the game slowly died out for me.

Aren't there some vanilla illegal servers out there for those that miss the glory days?
