That's definitely my experience too, and for me it provides the perfect balance of risk and reward, knowing that you are out if you get things wrong. For me, removing the markers is actually easier because it trains you to watch what the ball is actually doing. Not only are the markers frequently misleading, they also add extra information to process that will slow your reaction time.
I'm also convinced it's easier to bat with the ball marker off . You only have one decision to make which is the line ...then play the shot. The delay caused by your brain trying to process/identify the colour of the marker then the line then the shot just is not possible against fast bowlers , so you are then forced to premeditate.
With the latest patch the fact that you can play shots more freely 360 degrees without being as paranoid about the fielding positions (the ball goes along the ground) , means you can bat without any level of premeditation imo. Using pro-cam with no-marker raises the level of immersion as well. So i could never go back from pro-cam/no ball marker.
Your bad shots tend to be late , which doesn't get you in as much trouble as playing completely the wrong line , typically you just lose power in the shot . But your good shots, when you pick up the line early just feel crisp and powerful.
The most recent patches have made batting a whole new experience (for the better)
