Q. Why not just let casual players get rewards comparable to those from raids?

A. It would be almost impossible for us to do, and this is a philosophical decision. We need to put a structure in place for players where they feel that if they do more difficult encounters, they'll get rewarded for it. As soon as we give more equal rewards across the board, for a lot of players it will diminish the accomplishment of killing something like Nefarian. My favorite times in the development cycle are when there are encounters that are close to being defeated but have not yet been beaten. It really creates a sense of awe among the players that there is something big and truly dangerous in the world. But it would be very disappointing if the items found on Nefarian were the same thing you could get in your nightly Stratholme run. [Stratholme is a much easier five-person dungeon.]
