I can't tell you any good MMO stories of my own but I would recommend you check out Preach Gaming's "Drama Time" series on Youtube (the thumbnail of each episode is a goat wearing lipstick and mascara, don't ask why, I don't know). It's basically a show where Preach asks people to send him stories of the craziest things that happened to them in WoW or other MMOs and he reads them back over his stream. He uses a lot of WoW lingo but you can still understand the story fairly easily. Here's a link to the playlist. It's basically a show that has exactly what you're asking for. I love it and I'd really recommend you check it out. Hell, there's probably too much content there for you.
