They haven't done much to improve the crowd in the last 5 (or 10) years. I want the crowd to be just like real life. Screaming and going into a frenzy during clutch moments, making the hitter nervous (maybe shaking the camera a little). Reacting off the crack of the bat. Not waiting for a ball that is clearly going foul to land before they stop acting like it's a home run. Individual people heckling hitters (nothing obscene). Booing and leaving the stadium early when the home team is getting smoked. Maybe the occasional fan getting tackled by security for running on the field. Just little details that make for a cooler experience, instead of the same exact thing year after year since 2014.
