It makes sense, since if I recall, it's the knight conflicting class, which are noble only, but there's no issue if you use a writ of exemption, as for the starting slave, if you need to, go to a dungeon, use the shrine for breaking will (forgot the name, the tribal looking one with dominance) then using a writ. They become noble and able to use knight or paladin.
I'm sure your point is mainly that it's not as easily noticeable, however, I noticed it in the knights one due to flavour text underneath it when hovering.
