Only change I heard them mentioning is that some people complained that they were having trouble with "leading" the ball when passing. Clint said they tuned that.
I loved the passing in the Beta in that, when using the lead stick, I could throw the ball more easily to a spot, since the ball didn't seem as "tethered" to the receiver. I thought it was a major improvement and brought an increased level of skill and user control to the passing game. I am hoping they didn't over-tune this ability.
