Animations in Warband are best described as 'janky'. Blocks are literally instantaneous. I get that it's easier - which is the whole point. No real rotational speed limits for turning.
I've said this before, the animations in Bannerlord are no better. They're just slower. Movements are still odd looking and abrupt. Both games look janky and robotic, the only difference is whether or not the gears have been greased.
We're all struggling with variables in attack speed, best way to deal with it is practice with specific weapons - which is, again, a good foundation for a better skill cap. Input delays need to go away but the concept is solid and being improved.
You're awful at estimating the quality of features. No, the concept isn't solid. It's unintuitive, as players wouldn't know without explicit instructions, and the usage of it is obtuse. It's an objectively bad feature that is bad both from a high-level standpoint, and from a intuitiveness/entry barrier standpoint.
The "trend" with Bannerlord's bad changes is that they're universally bad, regardless of playstyle. Making things delayed is unfun at all levels of play.
There will always be a mechanical best in slot - the point of classes is that you can't always play best in slot. You want best in slot armor options or mobility you literally won't have access to BiS weapons.
The problem is that the advantages you choose are not of equal value, there's always the optimal choice and the crap choice. It's a terrible system that sacrifices everything good about what came before for a couple of absolute non-choices. If the "BiS" armour is a crap choice, it's not BiS.
Again, your argument is based on 'chambering doesn't work and kicks don't work so it's not as good'. Except everything else about it is better and while people don't like them, variations between attack speeds between weapons will be a good thing when chambering and kicks work. It'll be harder to GIT GUD than warband, no question. That's the point.
I love how you can't argue with anyone without strawmanning with "chambering and kicks don't work". The point is, countless other things don't work either. Fixing two broken things won't magically make the pieces fall in place, and that's fairly obvious.
