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.
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.
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.
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.
Im guessing your predominantly a SP player that occasionally played TG arena?
