Bethesda is adding a Legendary Vendor to Fallout 76 in attempt to solve the problem with unwanted legendary loot, as well as more opportunities to earn specific legendaries.
Discussing the upcoming Wild Appalachia update at the Game Days panels at PAX East, executive producer Todd Howard said (via USGamer) “We know the loop of getting legendaries, and people wanting the better legendaries and
getting the one they want. We’re solving that loop.”
