I think it would be nice if there was more to the baseball feature. Off the top of my head I would say that keeping track of actual player stats would make a big difference. Looking up players and only seeing batting 100 rating because that's the training level is not enough. I doubt the baseball feature is high priority, but it would only help with playability. There are lots of small things that could be added to this (not just baseball) that may or may not change actual play, but will give us more to help immersion in-game.
Thank you
