I recently switched to a BLM main after giving up on SMN for FCoB. Someone mentioned using a /facetarget macro to help prevent LoSing, something I had never used before. I made the macro and set it to my hotbar, and yeah it helps. My question though, is it possible/ a good idea to macro this to my abilities? I know macros with /wait commands at least prevent queueing abilities, but I wanted to know if macros without /wait commands still prevent queueing. I tried to test it on a dummy, but couldn't make out a difference.

ex of macro I would be using:
/macrocion Fire
/facetarget
/ac Fire <t>

Thank you in advanced
