In ST:TNG 2:16, in the Federation's first encounter with the Borg, Deanna Troi states:
We're not dealing with an individual mind. They don't have a single leader. It's the collective minds of all of them.
She then follows this up by saying:
A single leader can make mistakes, which is far less likely in the combined whole.
Based on this, it seems that the Borg were neither connected to, nor guided by, a single consciousness of the Queen, but were rather an amalgamated consciousness of disparate sentient minds. If the Collective mind was controlled by the Queen, shouldn't Troi have felt a single consciousness of the Queen, albeit divided amongst otherwise mindless drones?
