I probably won't macro Selene because she's a good girl who listens. Maybe Silent Dusk macro for those rare bosses who aren't immune to silence ( cough*CHimera*cough).

But for Eos probably a roused/Illuminated Whispering Dawn macro with steady at the end... just for one simple button push.

But hopefully they just fix the stances so that they remain in whatever stance they are placed in ( how it should be in my opinion)
