Its something id definitely like to see doubly so since they plan on having personal decisions of puritan or radical inquisitor leanings. However, Neocore has kind of done things differently. In the actual tabletop game, the crusader, assassin, and psyker are part of the main inquisitor's retinue and not actually an inquisitor themselves. So I'm not sure who we would have inside our retinue when those that would normally fill that role have been elevated to inquisitorial status.

I suppose they could be lower rank versions ie; almost like neophytes.
