If it is possible to fill up the factions with more lore or at least some more content like dialog content, for starters to say the repetitive order and the order of the phenox to get there trust etc buy doing things for them or building there buildings in the various settlements, castles, and villages would be good.

especally on revolutionaries you could try and win them over by pinning down what they trully want and if you can get it set up by policies to win them over you can essentially remove them from the game or have them join the faction that did the requirements for serious power of numbers and more.

hell anything to flush them up with content would be idea. would like to see what people say or at least have the mod developers respond on steam sometimes. :(
