I think they should get rid of Sic and Obey, and put in the 3rd "do nothing" stance. And then make it so Steady only uses their first ability (Embrace) on autopilot. That way, if you want your fairy to auto-use all their abilities (for trash mobs or easy bosses), you put her on Guard. If you want full control of your fairy, put her on Steady (since Embrace doesn't have a cooldown, I'm fine with it being on auto in this mode, but I'd also be cool with having to manually use it in steady as well). If you want her to stop doing everything (mostly for summoners/arcanists when they need to stop dpsing), you put her in the 3rd mode.

I've tried setting up keyboard macros so that the fairy stays in steady/obey mode, but it never seemed to reliably work - I think its because for Obey to work, you have to have an enemy targeted? And I keep the tank targeted.
