It's hard to get a Counselor and a Nurse DOFF if you're KDF. Common quality sell for over 5 million EC and Very Rare sell for 75 million EC. Are there other alternatives like maybe purchasing these DOFFs with Fleet Credits or Dilithium?
The KDF equivalent of a Nurse is a Medic, so there aren't any KDF Nurses as far as I know: The Medic has the specialties normally associated with Nurses. The KDF Counselor seems to be a singular oddity. There aren't any others that I've seen. I can only imagine that counseling sessions sound a lot like this.
As far as buying a KDF Counselor, part of that is simply that the KDF has smaller numbers of players, a portion of which are interested in doffing, and of those they would have to be willing to sell the Counselors they did trip across rather than using them themselves... and useful Medical doffs are hard to come by.
