As the week progresses all I see in Labyrinth are BLM and SMN DPS. The other body pieces that are split between two classes will only have to compete with one other person for their drop if it drops. You could, potentially, be competing with three other people for one item if you're not one of the lucky ones. That doesn't seem right to me. I run Labyrinth of the Ancients on two characters and I see pretty much the exact same drops as the OP and it's the very reason that MNK is the next job I'm gearing with Labyrinth drops. I will say that after running LotA repeatedly I did manage to luck out and get a Crimson Vest while in competition with two others that could've "needed" it. So yeah it sucks and yeah it's stupid but hang in there
