I'm very happy with it, released only 13 days after release of the game. The check swing is added, the pitcher stamina is fixed, the casual outfielder animation which I'd been scored on because of it fixed, and I already fixed the outfielder throwing power myself through edits. These were probably my top issues with the game, and they're already fixed.
Only way I would be dissapointed is if we have to restart our franchises for these to work, because if that's the case I'll just go with no patch.
2k can easily tone down the rocket arms through roster updates.
