Got bored and made this. Explanations:
Unarmed combat is a staple of RPG's, and will be a fantastic fit for tavern brawl and prison escape situations, should they be added in. Also affects kicks and bashes.
Slings are very powerful weapons, and using them requires a wholly different skillset to just throwing things.
Shield skill would bring back the "force field" in warband, simulating the character reacting to a projectile and moving the shield to intercept. Perhaps it could even have and actual animation for that. Would also improve your anti-shield capabilites, such as crushthrough and general damage against the shield itself.
Sneak increases your chances of sneaking into settlements, decreases the distance at which your party is visible on the map, and increases the amount of people you can bring to a hideout raid.
Persuasion is the third pillar of getting people to do what you want. Roguery is about intimidation, charm is about being a likeable person and befriending them, and persuasion is the littlefinger-esque manipulation.
Training is desperately needed. Currently, when you have a bunch of recruits you need to train, you're essentially railroaded into fighting a bunch of boring looter fights. The training skill was the 2nd most important skill in warband with good reason, and it needs to be brought back.
