For sake of space, I won't quote, but the guy 2 posts above me has got the idea. Simplification of what stats you want shouldn't be a huge factor of the game itself and how fun it is. Would you rather:
A. Take out a spreadsheet for every piece of gear that drops, and have extreme balance issues every time Blizzard changes a class and all those complicated stats change the stats making the class OP/Nerfed unexpectedly.
B. Not have to worry about gear as much and enjoy the game, and leave more time for blizzard to make content, in-turn allowing for more "fun".
In short, gear choice shouldn't be a part of the games difficulty, that just sounds outrageously stupid. The difficulty should be in the action it's self.
EDIT: The guy below me has the picture.
