You use them to minimize or completely negate high damage, one-shot, or knockback attacks so that you can simply stand in place and continue DPSing.
The only macro I use on BLM is /ac "Aetherial Manipulation <4> (healer), keybound to one of my mouse buttons, so I don't have to mouse over anyone, I don't have to click anything, I just push the button, and it zooms be back into the stack on t8 after mines or tower activations, makes you immune to leviathan slam/deck slide so you can keep DPSing, pretty much anything and everything.
