Alot of those aren't intentional like the small beams, the actual combat mechanics themselves are more realistic, like having to actually move your body with the swing to create momentum, in Warband there was no weight behind anything, felt like a god just effortlessly slicing through people. Warband lacks realism and maybe all the complaints are just people wanting something unrealistic because they're not used to realism.
If you need to move your entire body to swing a sword then you are either a toddler or have noudelles for arms.
Now with that in mind, record a video and do the same, but with a sword in your hand. Try not to kill yourself in the process, thanks in advance.
You have no idea what you've just unleashed.
