Why did they do that? I have no insensitive now to search for more hidden Docs (Dr. not paper). Was there issues with killing a DOC then locking yourself out of the inventory item?
It would be because of their changes to itemization and the whole level scaling stuff.
Before, Rippers and Vendors all had specific stuff in their inventory. Each with specific rarities (Which did mean that in Act 1 you could run around and get a full set of T5 Legendary gear before level 10)
With the change to level scaling they swapped inventories to level scaled stuff. But made them more generic so they all have the same inventory (Weapon vendors at least have some RNG as to what is in their stock, but the rarities will all be the same based on your level)
As such, all Ripperdocs have the same stuff available (Besides PL Ripperdocs, whom have the PL Iconic Cyberware available in addition to the regular stuff)
