BioV aren't a waste of points as they are designed at the moment because BioV cost the same as Courage and have a similarly low game impact. The issue is that BioV is typically used as a defining characteristic of a profile and as a defining characteristic it is not able to carry the weight. "But this unit has Hidden Deployment" works as a defining characteristic of a unit to set it apart as a comparison. So in essence, the issue here is that Bao are a low-performing trooper when compared to other units because Bao doesn't do anything potent enough within the context of Yu Jing or ISS to set them apart and their price is high for the sum total of their profile's expected combat performance. Which is to say that they aren't useless but that most people will rightly expect to get better value for their points spent on other units and certainly Bao doesn't perform well enough versus impersonators to be worth taking on that merit alone. If you put BioV on a profile you already like it wouldn't be unwelcome and arguably BioV as designed at the moment is designed that it would have a low-yield impact if it became as common as Courage. I wouldn't mind BioV too much on Celestial Guard, for instance, it'd add a point to their cost sure but it'd also add to the sectorial's flavour and make sure that I always have a reasonably decent unit for active Impersonation Discover on hand because I always bring at least one CG if able to. Given the scarcity of the equipment, however, maybe it should be an automatic success on Discover attempts and possibly even force the Model to be placed regardless of Impersonation level active.
