The overall number of items dropped at Davs hope per session have been reduced, which decreases your chances of a specific drop.

Where did you come up with that nonsense?
There are 10 points where materials appear at Dav's Hope - there are the same 10 places as there have always been. The place has been given a make-over, ground slopes differently, the Hobbes sign has been corrected, base comms uplink no1 now works again.
The only "nerf" was that the bug that allowed you to access the main data point to farm data mats until the cows came home is now returned to it's normal state of access once, then it says "accessed" until some timed reset (I suppose the normal 2 to 3 weeks).
I don't know why people are posting this rubbish about Dav's Hope being now unproductive - is it the Kremlin's disinformation squad getting-in some practice?
