I got my first drop in hour #23 of grinding, but even I still don't think they should change the drop rate. I'd much rather they change the structure of the quest to something you can make steady and assured progress on (slowly).

For a quest that's supposed to be a time sink, RNG is a bad way to do that. The way it stands, it's a time sink only if you are unlucky, which is just bad design. It should be an equal time sink for everyone.
