I don't disagree at all, but that opinion on the matter got blitzed by 1,001 people complaining they couldn't find enough Fians in a reasonable timeframe. All sorts of people complained about it too, not just on here -- Steam forumers, Redditors, Twitch streamers, YouTube LPers -- basically everyone hated it when nobles were hard to get. And it tied into other complaints, like leveling Leadership to get the Discipline perk at Leadership 150 so you could turn bandits into nobles. Almost nobody would've given a rat's ass about Leadership's issues with leveling if it weren't for the perk.
So TW just nuked the rarity and made it easy.
