Games are too long. Why does a batter have to step out and re tighten his batting gloves after every pitch? Even pitches he does not swing at?
Simple — you don’t pitch within 20 seconds, it’s a ball. (Maybe if they really want to make pitchers pitch, call a balk.)
If the batter steps out, it’s a strike. Maybe you get once, to get the signs from teh third base coach, but after that, definitely call a strike.
