I posted this on the OS Sliders. As of this post, we have our beta set posted as well. Here are the base findings in which I was able to get the midfield in a better spot. These examples were pretty much default except for 4 total values changed. We've since changed multiple values for the beta set.
Rotherham - CDM||Macdonald. Notice how deep he gets and how he latches onto runners around him, but not to the point he follows them everywhere.
Checked his instructions - and everything is default/balanced. Team is set to balanced as well.
Crystal Palace - Milo & McArthur. Here I need them to latch onto runs by James and Doucoure, which they do. As a result, they are properly deep enough and not standing idle at the top, or near the D. Both players are set to default instructions, except McArthur gets in the box for crosses.

Crystal Palace - Milo & McArthur. As I mentioned, this is not 100% automated. You will still need some form of input and responsibility to control your defensive duties. In this clip, I could have put a better effort manually, but was testing so I let it go full-auto essentially. As you can see, Milo and McArthur are in the right spots, but they are latching onto runs by James, Allan and Doucure at first. Even though I would have preferred McArthur follow Allan into the box, it is still a good sign that there was a pass-off animation to represent a zonal look.
