Here are the current hitting issues from my POV:
#1 - Early swings are OP. The best exit velos are when you're early to perfect. There is also an inconsistency with very early/early swings resulting in balls put in play but just early swings resulting in foul balls.
#2 - Timing window is too big. No flail animation should result in a foul tip. These ties into making very early/early swings OP. Guys can just wait until you throw something harder and run into one. It's too hard to strike people out...rather it's too easy to make contact with horrible swing input.
#3 - The lack of base hits and exit velos when you hit the ball just past the perfect point is crazy. That swing should result in more hits...especially compared to early swings which result in bomb after bomb.
#4 - Sinkers are still a problem. They are unnatural and resemble off speed.
