My suggestion would be turn off the ball marker (the red/green/yellow/blue) circle around the ball. Just go with the pitch marker (I'd suggest the black colour not the colour coded option) Reasoning being:
I noticed in DBC 17 I wasn't doing anything other than reacting to the colour. Red - back foot, everything else - front foot. It is, in my opinion, a button prompt and completely removes the skill of judging length, which is a key part of batting. Fine if you're a casual player but I like to have a more in depth experience. And, like you say, it can lead to you not always playing the shots you think you should. That can still happen without the ball marker of course but it feels like a mistake by you not a mistake based on your reaction to a guide given by the game. You're more likely to learn from that mistake too.
You have to actually work out how the ball is bouncing off the pitch. This is more cricketing skill than being able to react to the colour of a circle. There is a lot more variation on certain pitches and you will, as a batsman does IRL, work out when to play off the front and back foot.
Personally, I like having as little clutter on the screen as possible - same reason I'd like to have the bowling hud disappear after I've selected my delivery. It's far more enjoyable to bowl when you are doing the footwork and release based on the bowler movement not on the position of a meter.
You might consider changing the leave button, I've always liked it as R3. My thumb is always on there so it is easier and quicker to play a leave than moving to another button.
It might take a bit of getting used to, maybe have a go in the practice mode, but it's such a better game without the ball marker.
