Apparently the prices will get fixed according to various comments i've seen on facebook.
I have to wonder of Mr Hoare was high when he thought it up, I get that being able to tailor your warrior to your opponent is useful...but really the prices are not at all worth it for one battle, who has that kind of credits to burn?
Also some of the new bounty hunters are not all that effective, Eyros Slagmist for instance, while very resilient, only has a laspistol, for his price you could permanently hire a ganger/champion with much better weapons for far more bang for your buck.
What you're really paying for is a couple of weapons early (ie the boltgun, which feels like a con) and knowing in advance what skills they have.
