Blizzard introduced rifts and loot spread over all the game so that people dont grind the same spot again and again. Your idea of distributing certain items on certain spots would totally work against that design idea.
difficulty : d3 was much much more difficult in the beginning. People did not like it. Also, you had to play trough the game once on each difficulty, people did not like that either.
tempering : no matter how expensive, the nolifers will just max out every stat on every item they have. It's just a resources sink IMO. If you are worried about items dropping with bad stats, we could always change the range in which stats can roll.
