Very, very few games along these lines DON'T have that same exact problem once you learn them.
Probably true, but I doubt it is to the same extent as Bannerlord. Go have a look at the forums and see what bugs and missing features people have been asking about for years. They just half-ass shit and constantly introduce and re-introduce bugs.
It's much prettier than Warband, of course, and adds a lot of QoL to the UI but it is missing a lot of the features that gave Warband its charm. Could have been amazing but is instead mediocre.
That's just my opinion so good for you if you enjoy it. I've mostly been waiting on them to deliver real content for a year or so.
