Are you sure about this? I have nothing to base it on but i thought if i set my team attacking but lets say i want to keep my LB AND RB from going forward too much then placing a blue arrow on them will mean they are more like "balanced" mentality.
Basically i thought it will set the player one step back for blue or one step forward for red from the overall team mentality?
i noticed i dominate the mid more when asking my fullbacks to attack .. so it could be true.. as I think we are starting to outnumber them .. same for my AML/AMR when ask them to attack, i lose possession
