I would suggest going back and replaying Warband. Your time is pretty evenly split between talking to lords, doing stuff for them to try to get them to like you, and fighting battles. In banner lord, that's absolutely not the caseUnless you expect TW to be able to develop an entire additional game (CK3) inside of BL, not to mention turning BL into just CK3 in the process, that's just how it is. The game's about pitched combat, it's gotta have pitched combat frequently.
