I'm going to be honest with you i really enjoy both sets because they both hold up pretty good in terms of realistic challenge.
I think if these were titled all pro or all madden you'd see more feedback but pro level will sort if scare people off because it's generally viewed as the easiest level but IMO these can hold up just as good as any all pro set i was to create because of the balance of the slider setup.
As for the difference in the slider i saw a little more movement out of the cpu qb in terms of avoiding the rush on version 2.0 and my wr's other than dez Bryant struggled to get seperation on version 2.0.......not sure if it was the 100 threshold or wr catch being at 40 which takes away a significant amount of warping to the ball.
On the 1.0 version the CPU QB really makes quick decisions with the ball and can sometimes look elite especially if you don't get pressure up front but i think that is tied into the qba being t 65 which seems to also boost their awareness on pro level slightly
While most guys are lowering the qba on the higher levels i have the luxury of raising it on pro level or leaving it at default 50 because it allows for more downfield throws.
I'm not worried about high completion percentages on this level because qb accuracy ratings seem to play out well on this level for the cpu
