Well that's the logical error that's been bugging me, dvang, having a career entitled "Inquisitor" has caused a good number of people to assume that it's mandatory to be a memeber of said career to earn a Rosette. The ongoing argument is that Inquisitors are far too diverse and interesting to be bound by a single common skillset as defined by the Inquisitor career the Ascention book, and that the Inquisitor Career is, while valid, also generic and not necessarily appealing to every Inquisitor as their choice of pregression and therefore should not be forced on the unlucky party leader for the sake of, well, nothing . And just as importantly it has been pointed out that there is absolutely no impact on the mechanics or stability of the game whatsoever, as they were intended for just this sort of thing, rather than Influence being tied to one class as it would have been in an "Inquisitors must take this thing" scenario.
Then angry conservative flaming happened. Such is life.
