I use these for all of Eos's Skills (Whispering Dawn and Fey Illumination), and I am not sure how people don't. Often if she is moving or casting and you just hit a skill, it doesn't go off right away and you have to button mash. Swapping her from steady to guard or vice versa interrupts whatever she is doing and the she does what you want her to do immediately.
