Is that me or the ball seems to lack weight compared to last year game ?

consistency just isn't a thing in the game. I have no idea where pci placement, swing timing and pitch location has to do with results. You can have the exact thing on all three things and get a different outcome each time. One time it could be a bomb, next a pop up to outfield and next a grounder to infield. One result doesn't seem to be more prevalent than other except on say early swings.
