Why are takedowns so laggy and inconsistant in bf6 unlike in previous tittles?

Here is another clip which kinda shows the whole pain of takedowns where you actually have to commit to them instead of mindleslly blast the person with a gun.

Also for this clip i have a question, why does the knife type melee sprint speed increase bonus doesnt affect the crouch sprint speed? Like you only get the faster sprint speed only if you are sprinting, if you are crouch sprinting it doesnt give its bonus to you, like in bf4 the you got 10% maximum sprint speed from the field upgrades and thats it there were no crouch sprinting etc, worked flawlessly, but in bf6 the knife states "Increases sprint speed when equipped" meanwhile it doesnt icnrease the crouch sprint speed, even though it is a sprint and should be technically increased.

Because if we follow the logic of "crouch sprint is not a sprint" then the Spec Ops training path lvl 1 "Gadget Awarness" should still show the gadgets when crouch sprinting, but it doesnt because you are sprinting, which is like, why does the perk count crouch sprinting as a sprint, but the knife speed increase doesnt?

Here is another clip, this one is the worst one  yet i think, 1st guy who is reviving who gets 1 hit instead of being takendown and then the 2nd guy who was prone gets 1 hit, then 2nd hit tries to start the animation but it kills him, like how, they arent spinning, they arent doing crazy movement they are literally standing still and takedowns decide to not work.
