I'm not surprised by this. Before the patch I was playing with Whosnext's Pro set and in that thread he found the same thing, lower OPI made the WRs much more aggressive to the ball. Also, higher DPI seemed to make them more aggressive. We were using 10/10 for the DPI/OPI and the battle for the ball and the animations were really great. I haven't tried that set since the patch but plan to give it a test later this week. Overall I thought the game felt much smoother and the animations were far better on Pro, not sure what the patch has done to that.
