As far as the disallowing of the shift next season, I have no problem with that because just like lowering the mound and employing DH's it will add offense to the game. However, if I was putting this new rule together, I would allow a team to use the shift a certain arbitrary number of times during the game.
Hell, MLB has numbers for mound visits, how many batters a reliever must face, and next season how many times a pitcher can throw to 1st base.
Just my 2 cents.
