The cover system is as broken as it was in 5, and you'll never use it, given that everyone has such awful aim that you can just run around the room aimlessly and remain hit free 95% of the time. Why do I need to be aiming to take cover? That's stupid.
And while I'm on the subject, the controls overall are so astoundingly convoluted that even a slide or dodge takes at least three separate buttons to complete.
Good luck with that.
