People need to stop listing random chests they found these items in, because any chest/container in the game world can spawn any weapon. What's important here is that certain enemies have a higher chance to drop certain legendaries. That information is actually useful to people hunting for a certain legendaries. No one cares that you found such and such gun in red chest under the stairs behind a marauder in Thousand Cuts while playing on a Tuesday and wearing your lucky boxers. Then again, I've never heard of orcz.com and it looks pretty janky, so go figure.
