Journal of Justice could have easily been reworked instead of removed
Journalists from every faction could have just written news about factions and champions without the Institute of war or summoners in mind. Even if some champions are legends and are very unlikely to be seen by commoners, there are a lot of champions who are political figures and criminal figures. And for the mythical champions there could be sightings, survivors, or other champions who could talk about them. Just a thought.
