1. Adding filters when picking your squad. (Great quests, but very hard to find that one player that can give tickets, or counts for a certain team)
2. Add stats for the computer teams you play. (I know they have your counted stats saved, but it would be cool to see which pitchers you do well against and which you struggle with)
3. Season Mode in Diamond Dynasty where you can take your squad and fill in for an actual teams schedule for the upcoming season, then play the whole year.
4. Sidenote - (Bayfront Park is really cool, but the amusement park should have lights on during night games)
Anything else that people can think of feel free to add
AND BTW. probably none of this stuff will make it into the next game, but they are just suggestions
