I honestly hadn't thought about how balanced, enjoyable, and rewarding the class system is. Perhaps I have been mistaken. Thank you.
Maybe a way to expand on this system would be to add naval combat. Boats are philosophically aligned with Bannerlord's design principles. To illustrate my point: you could 'main' a boat, and learn it at your own pace, enjoyably. I would also love to customize my Viking longship; I could add a frightening figurehead to the front, so as to frighten my enemies in a balanced way.
I could picture it now. There's me, in my Viking longship, ramming plebs in rowboats (the 100 gold option). Then, I collect enough moneysacks and add a cape to my boat. Goodness, it would be so cool to do skirmish on a boat. Please, taleworld, give me boats. please
