Which instances/raids are disappearing in Cataclysm?

That's really unfortunate. BRD remains to be my favorite dungeon. It doesn't even take very long to do an emperor run if you know where you're going. None of the burning crusade or WOTLK dungeons even compare to it. They're all so tiny, linear, and boring. What ever happened to instances that really made you feel like you were raiding an ancient underground city?

When I was solo/duo playing, I used to HATE BRD with a passion. TOO LONG. But now that I'm multiboxing, it is definitely one of the more fun places, especially with groups that excel at AoE.

Regarding level design, I totally agree that it is (and BRS, too) probably the only place that feels massive and ancient. I wish they'd do one something like the Lost City from Thief: The Dark Project.
