If you're going to include a restructuring of the library, then do it for everyone.
You can include restructuring in games where one player controls a Castle, and it will be an additional advantage for the Castle; there is logic in that.
Against the backdrop of Conflux, Necropolis, Dungeon, and Archangel factions, strengthening any of the clearly weaker cities is a good thing.
I would like to strengthen Inferno, Barbarian, and Swamp factions as well, but we don't know how. Here, there is an opportunity, so why not use it?
And what is the logic of including it always? I don't know, anyway, what the logic was behind deciding to disable the library restructuring. :D
If anyone knows, please write.
