Takedowns need adjusting.
Takedowns are a letdown.
Why can't you do a takedown on a crouched enemy?
The angles you can perform takedowns from need changing, takedowns need to activate from the sides and back, not just the back like this:
you have to literally be hugging the back of someones helmet for takedowns to activate, this isnt practical when you are dealing with a moving twitchy enemy and leads to frustration, I have only used the combat knife so far so cant speak for the other weapons.
The hard part, especially in this game is getting behind someone undetected, if you get behind someone and you are facing someones side a takedown should be possible, right now if an enemy moves an inch the takedow doesnt occur and your busted for all your effort.
I did make a thread in beta feedback during the beta where I went into more detail but it seems it either got missed or ignored.
