I know it's not entirely a conclusive test, but I just killed 350 peach tree's with only 6 DB's dropping. I got 5 elder branches, 2 OBB's, 3 Banana Juice, and 42 Royal Jellies....But only 6 DB's? That's a grand total of 1.7% drop rate on the DB's.
Now, I could've had one serious streak of bad luck drops...but...really?
Has anyone else had an issue hunting them there?
Also, could you CM's check and see if the rate was accidentally lowered at some point?
