All your problems are solved in Season 6. The drop rate is much lower and only items worth getting are ancestrals as they are the only items that can get two affixes tempered, and their drop rate is only .01%, and rarely drop from Tormented bosses (I have farmed dozens of tormented bosses and not found one in PTR), so in S6, you can either pick everything up and just salvage, or you can just leave it. After 12hrs of farming Torment 4, you may find one if you are lucky, and it will show immediately, so you can pick it up and leave the rest. You have spoken and Blizzard has listened.
