I'm not sure if it was supposed to be in the game, but realistically, how can they make ambushes a fun and fair thing in Bannerlord? If it's something only a player could do I would rather not have that feature, since it would make the game even easier. If both the AI and the player could do it, would it provide a fun gameplay experience? Would it be RNG based whether the ambush attempt fails or succeeds? If not, how meaningful is it as a feature if it can be avoided somehow (for example if it requires scouting level 50 to avoid, what's the point of having lords with a scouting level lower than 50, or building your character without having scouting level 50 in mind)?
The same issues present themselves when we also talk about intrigue and assassination mechanics. Even if the game speed was 3x the normal and we could play as our heir in a reasonable timeframe, would it really be fun if the character we created and levelled up lovingly died due to a mechanic that would likely be based on RNG (if we take CK3 as an example). Or would it be fun if we could kidnap enemies through an intrigue menu rather than capturing them after combat? The truth is, it's hard to design and add new content into a game, even harder if you're the developer of the game since you will have to maintain and balance that new content along with the base game and possibly balance it with additional mechanics you're planning to implement in mind.
