This is pretty much just for Flyfot and Bigguy.. but after testing it I found it to be rather nice

This addon will automatically announce in yell, party, raid, or say if you missed casting tranq shot or not.. this way, you don't have to stop DPS'ing to notice if your tranq shot missed, and you also won't need to setup up macros for tranq shot.. you can just use the normal tranq shot button.
