They may be functional and actually drop items, but they do not drop the correct amount of items you should be getting.
Here's an example of our "The Worm's Turn". I've done this 4 times now but no longer have the screenshot of the first 2.
I have always gotten only 4 items (1 equipment, 1 scroll, 2 trash items) when I should have gotten at least 6 (7 with gil) items with a chance at getting more than one (up to 3) equipment and more than one (up to 2) scrolls and 1-3 trash miscellaneous items.
Here are examples of retail "The Worm's Turn". I was only able to find 3 videos on it but only 2 successful runs and 1 failure.

On this run they get:
Gil
Nemesis Earring (Equipment)
Earth Mantle (Equipment)
Strike Shield (Equipment)
Refresh (Scroll)
Black Pearl (Trash misc item)
Erase (Scroll)
Please consider revising the loot table of this BCNM, I don't know what more proof you could need to show our current loot pool is not correct. The gil isn't necessary but the "reward" you get for the amount of time, effort, and farming needed to do isn't worth it. Official content should be more rewarding, especially since the OWNM can drop more and better items.
