I just recently discovered this. It's a huge QoL improvment for me when I'm Cleric Stancing. I haven't seen it posted anywhere.
/micon "Stone II"
/action "Stone II" <t>
/facetarget
Basically what this does is make your character face your target everytime you push this ability.
What is it good for? Well, have you ever lost LoS because an enemy runs past your incredibly narrow field of view (Thornmarch comes to mind)?
This macro prevents this if you spam the button during cast.
