They even removed chambering.
but they didn't. It's a bit harder and needs a bit of a buff, but they never removed chambers
but yes I also don't like that its so sluggish, with a little bit of footwork you were able to fight halfway decently against a crowd, in bannerlord fighting against 2 is quite a challenge, against 3 a death sentence (unless they're really stupid). But a lot is just stuff getting used to, when it comes to Warband Vanilla, it is pretty similar for me, that's why I got high hopes in mods.
stamina
thank god we didn't get that, that would take a lot out of fun out of the gameplay. Stamina has been discussed a lot in the past years (in all its various ways of working with the gameplay)and in the end the conclusion was always the same: it just wouldn't work well
