Anyone else feels that Discovery needs an another big bad guy faction?

That is not how Discovery decided to roll so far.

 

It may have been! The creators went out of their way to not mention who the species was but from virtually the moment the episode aired there were theories that it may have been humanity's first unofficial contact with the Breen. It would have been cool if it were as it would add the element of harvesting humanoid lymphatic fluids and other bodily secretions to the list of things the engimatic and cold-climate Breen did.
