I wouldn't say turning auto embrace specifically is that important to me, but turning individual skills on/off auto in general would be nice. I mean, sch puts a nice spin on it, but really they blatantly lifted arcanist from warlock. And warlock could do that. You should be able to turn off ifrits stupid stun or micro contagion without having to micro the other abilities. Or let selene handle the buffs but you can still silence.
