[@Mangrale] Just want to throw it out there that Priests in a mercenary outfit would make plenty of sense in universe, as a person's healing power derives from their faith, but that does not necessarily have to be faith in something holy and just. And even if you wanted to play that kind of priest, there isn't anything keeping you from writing a backstory that justifies them becoming a merc for any number of reasons. Essentially, those with healing magic are called Priests (or Clerics depending on the game), but that does not immediately tie them down to being morally upright members of a church.

And it is also worth mentioning that any outfit with plans to stick around for a hot minute would definitely invest in bringing on a few individuals dedicated to healing, seeing as their guys are far more likely than usual to end up with more holes than the human body is typically meant to have.
