The gameplay is too fast for proper chamber usage. You move and strike way too fast like a super saiyan is this game.
To make chamber viable you need a more slow gameplay like mordhau where mastering chamber is doable and has an impact on the gameplay.
Currently on bannerlord this is just luck. I don't see how they can make chamber playable without slowing the gameplay, but they will never slowining it cause every very high dpi ballerinas will whine
