Your MF probably sucks. 5 inventories for 3 runs? **** I find 5 inventories of 62 - 63's in one act 3 full clear in 1.04.
Since your MF sucks, because you are a scrub, you are going to get lower quality items in addition to lower quantity. As it does affect the number of affixes you'll receive on each item. (including legendaries, which can spawn with additional affixes).
All of you QQers really need to stop sucking at this game. Get your MF maxed. Clear out the ENTIRE act 3 in 1 hour. Then tell me drops are bad. I found 7 legendaries yesterday, pretty typical. Only 1 worth $10 (only 1 I would consider keeping for myself) but eh that's because current legendaries are still mostly trash (though it was a large improvement over 1.03). 1.05 is going to boost both legendary quality and quantity.
And you really cannot determine an item's quality by it's worth. A GF helmet with socket and 30 dexterity goes for 500k +. A GF helmet with socket and 150 intelligence goes for nothing.
The number of usable items you'll find will increase. The number of sellable items will always remain the same no matter the drop rates. The number of items used to farm MP10 will be few and far between, but the numbers for farming MP1 will be numerous.
But I expect nothing less from you Kenshi than stupid negativity.
