Cait Sith HTMB Not dropping items

[Zohuro]

I have recently started to repeatedly do the Caith Sith HTMB battle. I do not have any of the items from this fight. I have attempted more than 35 battles so far. Other than the 3rd battle that dropped the Cath Palug ring, for the last consecutive 30+ times, no equipment item has dropped. Other than the first and most recent battles that were on Very Easy, every battle was on Easy. I subjob /THF and have 2 TH items for a total of TH+4 but nothing dropped. Is this drop rate usual? Is this part of the game working correctly? Other people reported much higher dropped rate. This has been extremely discouraging. I understand for an MMO game, the drop rate can be low, but this is becoming too low. Am I missing something? Has there been changes to the mechanics affecting dropping of items to this battle?
