I'd be worried about people who speak of returning to the glory of vanilla raiding. If you've read articles about "glory day" nostalgia, there's a lot of love for broken, archaic design. Something along the lines of "Oh man, you'd enter a dungeon and it made no sense of where to go and then a boss would spawn on top of you and wipe you! It was so great!"
I hope they don't mean that and I know they don't mean the crappy dungeon design that started up towards the end of vanilla because Cata is redesigning many of those.
And PD, I wouldn't bother with your Shaman. *dons Kanye mask* Blizzard doesn't care about Shaman peoples.
