My Idea: The Dev team puts together one of their personal custom built out characters for the players to see like the Soviet notes. But each custom build has a little bio story/lure as to why it was build the way it was.
Could be part of a special event like they have for Halloween or the anniversary event. Or a DLC. Players collect them like the other collectables and could be anote collection.
That would generate a lot of buzz on the forums about why the build out could be better for the aged players and useful info for the novice players to study. A screenshot of the skill tree and which skills to pick in order of when to select the skill. Could be one of each specialist that can be built. It would have a story line of the first of the resistance’s fighters and a bio of their skills they used to fight back the machines. Could even add some lore into their super abilities.
