Some people set it so that only their debuffs display on the mob, so it could be that.

As for what I like as a DRK, a SMN and just someone to give me some TP. NIN, MCH, new AST Spire, whatever. Having a 60 SMN myself, I like it when I have a SMN in the group when I'm tanking because all the groups of regular enemies die that much faster.
