BRD was the best dungeon ever made by Blizzard. Every other dungeon ever made after BRD has been a bitter disappointment by comparison.
You can tell they put their passion into that place, which is more than can be said for any of the instantly forgettable hallways created ever since TBC.
Not every dungeon has or can be BRD, fine. But even the mega dungeons are not nearly as great as it was. They should try harder. We should get at least one BRD per expansion.
