I've noticed two changes which I think are very bad for the competitiveness of the game and go against reality too, (I'm a baseball purist, so I desire only what agrees with real ML baseball.) At the moment IU can only recall one of the two, but as soon as I remember the 2nd, I'll post again.
1. If you take a guy off the 40 man roster now, you don't have to pass him thru waivers, even if he has no options...you can simply put him in your minors...so now teams can hoard decent players and not allow the weaker teams a chance to improve.
I think the new developers are doing a good job, but I think they are getting a little "loose" with the games. Keep it agreeing with real ML rules...don't screw it up.
