I am on the third floor of the endless paths and fighting the Ogres and Ogre Druids that are found there. I've hit and crit with dominate on both the Ogres and the Ogre Druids, the effect lasts for all of a fraction of a second and then they lose the dominate effect. I'm using Puppet Master with Grieving Mother.
It's really frustrating in what is proving to be a difficult fight. I'm on the latest patch.
