I'm playing 3-2-2-2-1 like this:

Team mentality: Attacking
Focus passing: Mixed, depends on the formation of the other team
Pressing style: Own half
Tackling: Normal on weaker teams, hard on stronger teams
Passing style: Mixed
Marking style: Zonal

Force counterattacks: Off
Play offside trap: Off

I don't use any arrows while playing 3-2-2-2-1, it makes no sense for me. My team is doing very good without arrows.
