I don't think two paragraphs is too much content for an IFF infocard, and most of the new Gallic infocards I've written thus far have come out in two paragraphs around a similar length to the Vagrants card. Would be nice to shave the HF card down to two, I agree.
I quite appreciate those long infocards and do enjoy reading them.
If they were to be shortened, I'd only approve of that if the information would still be available somewhere else. Like a comprehensive lore article about said faction.
