Dribbling controls when in Isolation. When I got the ball and cleared out to go one on one vs the defender I had issues setting up the size up. I wasn't sure if it was me, but I had problems gaining any kind of advantage when face up 1v1. I've noticed this problem when watching others as well. They'll get a clear match up in their favor and they couldn't pull off the moves. in Live 16, if you get iso'd onto a big man, you can easily take advantage. This could also be because of the new timing on offense and defense, but with more hands on, and a practice mode (tutorial) it should be fine.
I've had talks with another Game Changer and he said the same thing about the dribbling. He said it was too clunky and not intuitive enough, which I agree with. There was a similar issue with Live 16, but they cleaned it up as the game progressed.
Another is the slow shots animations off the dribble, especially the step backs. I just want the shots to flow well after a killer crossover, I felt it was too slow compared to the initial move.
Since June I've been thinking about the controls, just so they can feel fresh in my mind when the demo drops, but these things really stood out when I kept going back and thinking about it. The set shots to me are fine, just better transitioning animations after dribble moves is what I feel needs improvement.
