"Bloody Murder" drop rate in Aurum Vale

Time: July 10, 2015 around 5:30 PM
Frequency: Consistently over the last week and a half
World name: Balmung
Character name: Nazeru Auronas
Monster name: Miser's Mistress
Class/Level: Monk/60
Party or solo: Both
Area and coordinates: Aurum Vale
Steps:
1. I have consistently been running Aurum Vale as a "Undersized Party" both by myself and with friends, for the MCH weapon "Bloody Murder" which the lodestone states drops from Miser's Mistress, at the end of the dungeon.
2. I have seen every other weapon that drops in Aurum Vale do so, on at least three occasions each. "Bloody Murder" has yet to appear.
3. My luck is either horrendously bad, or the drop rate needs adjustment.

I ran this with KarmaWalker probably a dozen times, minimu. In that time I saw weapons drop for WHM, AST, PLD, DRK, BRD, and MNK, plus the shield. Several more than once. I have four morbol cards, they have 19 last count - we have run this a LOT.

I have to agree - Seems like a bug in the droprate for Bloody Murder.
