At the moment the whole system is buggy.

If you don't place your AML/AMR close to the middle of his "field", he plays a center position. If you put your ST too much forward, he plays AMC.

I put a DL as close a possible to the ML field, he didn't play offensive. My DR at the middle of his field played much more offensive than the "offensive" DL...

No learning required, before they fix the punsh of bugs.
