Happy birthday, Sir Ross Scott!
Here's a story in a nutshell(of which there are many, many more);
I played WoW since vanilla release in 2004. I've got a ton of stories, but one I can share without feeling like I butchered it is the story of Popsicles, the guild/raid leader of Nerve on Chromaggus-US East. Highest end guild on the server, and top like 25 in the world in vanilla, maybe top 10 (I know in BC they were for one full raid tier).
Anyway - They were in Naxxaramus and they had issues trying to kill Thaddius, who's mechanic is putting a positive or negative charge on players (like voltage charges), and it requires them to group accordingly WITHOUT crossing paths with other players who have the opposite charge.
One night, after a full 8 hour raid, this happened.

Do enjoy.
I've also got a story about a woman who tore apart a marriage in my raid guild in Wrath (World 68 HLK25 kill), and then tore apart the officers, then left to join Vodka, and then destroyed a relationship and guild over there. Long story short: Titties.
Edit: I also used to play Conquer Online 2.0 a TON before WoW. The power struggles, Kill on Sight tags, server black lists, and rage events are pretty amazing too. If you want anything specific, I might have it. Let me know, Ross! You may have to force an email to come my way, I feel this post may get buried and I won't know if someone responded to it.
