Look at what I found, one of the 1st articles that explain the old raids in wow. Now thats epic, it even mentions that you have to be certain bosses in order to face stronger ones, not the casual crap we have now were everybody needs to see 100% of the content. Enjoy:

My favorite part is this one:
That actually happens in every dungeon - not just the raid areas. I added Blackrock Depths to the current beta a while ago, and the testers went nuts. They said "This is the hardest dungeon ever. I can't believe how hard this is tuned. This is impossible. There is no way it can be done with a group of five."
So I posted on the forums and said, "Let me know how you feel about it in a week." Sure enough, a week later, groups of five were beating it. And now it's attacked regularly and beaten pretty easily. They'll figure it out, and I think knowledge is the best advantage that they can have. Plus, we can make higher-tiers harder just by playing with the numbers, and then players will have to ramp up in gear and resists to beat these higher challenges.
Today, if you wipe once in a dungeon the first time you enter it, the casuals will start crying.
