If damage were more worrisome like in some sessions of 2238, Medic/Field Medic would be desirable.
Like being unhealable for a while after respawn, but Medic/FM could fix that.
But then every gang would just have a Healer alt on hand for that.
Possibly make Medic/FM Support Perks with similar requirements. With a lot of expense/some questing involved.
Dr. Fung, Doctor in Broken Hills, Vault City Doc (in vault) needed to acquire.
Maybe they want caps, special materials, samples of various monsters, data from Talchem, special medical equipment (taken from Vault infirmaries and requiring HQ EP to fix up), health reports from many areas (ala Doc Andrew), etc.
