How's this, from your first active tier onward have individuals or creature with no aura affected and introduce grimm due to them being more unknown in this aspect from tier two. Well, the thing is that the Grimm does not have Aura, which is, as they said, a manifestation of one's soul. So if the user's Aura flow through the nervous system, another Aura will very likely fight such intrusion like the immunitary system attack foreign bodies. That's why the user must have great control of his Semblance and how it flows on the target's body to control an individual who still have Aura, or even one with none of it left. For the last one, I don't think that, when an Aura shield is broken, there are no remnants of Aura through the body, so I putted it in Tier two and not in one.

To conclude, what I mean is that is is easier to control someone/something with no Aura as it require less mastery and ressource than an individual with some aura left. So whatever system directs the Grimm, it seemed to be more hack-able than an human/faunus because he lacks an Aura, which acts like a Firewall.
