Leaning and crouch sprint..

Not really necessary. played every BF game and i hardly used those features, they never worked as intended anyhow. but to those that want it i understand

wait there's leaning? how do you do that tho?

Highly disagree, crouch sprinting is one of the best added features in BFV. Proning on back was great as well.

Make sure you have auto lean tuned on in options. Push up close to the edge of an object or corner and when you look down your sites you peak the edge.

Completely agree. I think all the tactical options should be left in the game.
