The more decisions per second and better behavior by GK and defenders to crosses are the biggest pieces for me. Those are the two biggest issues with FM16 that have kept me in the brink to go back to FM15 (and I've gone back to FM12 if I knew how to get the change tactics buttons in a match) all thorough. We don't know how much it's actually solved yet, but that means we can hope all those stupid, buggy goals will be gone.
