Well... Not necessarily. The earth is full of crazy bitches, while a Zombie is way more interesting to an independent research facility.
So a BL witch is nothing more than a crazy bitch plucked off the street?
.... ....solair, I love your work, but please review your lore : witches are psi trained, higher up, top echelons of the black lotus : They have training, sensitive information, and are MUCH more limited due to the time consuming process to create them
Consider the following : Supply and demand.
Witches : Very limited in supply, since they are supplied (CREATED) in proportion to demand, with training, ect : They are essentially like xcoms commisar officers ; rare, but very important. Thus, losing one would be a big hit, because you need to train another, and you just lost a high rank officer
zombie : VERY common supply, and easy as hell to aquire, for anyone with a few guns and balls. Theres plenty to go around, on a global scale, and its much easier to aquire 100 zombies than 100 witches. They might also have demands, but keep in mind, supply is VERY common, and not exactly difficult to get either. Its much easier for someone, be it a big organization, science institute, or even a common man, to acquire a zombie, then a live cult agent, so I figure it would be less.
Any science institution who could afford 20k could probably afford to pay any merc to bring in a zombie corpse for less, while abducting a LIVING HIGH RANKING OFFICER, of an EXTREMELY DANGEROUS CULT, is quite a feat, which should reflect a higher price.
....I think this should apply to all cults, really. Anyone of higher rank should have higher ransom price, at least by some.
And beasts should have a lower sell price, (For corpses...maybe higher for living?) as they really do seem a bit OP. Like I said, a 50 zombie hunt catches a cool 1 million dollars in corpses alone.
