Own half means the defenders will not cross the half line of the pitch its good for all mentalities and if you want some players to go up u add red arrows, in your case you attack flanks so you will give the DL/R red arrows and the DMC will simply counter and rival AMC and will be like a 3rd MC when your team attacks(you will noticed many counter attacks by your team cause of rivals ball lose)
Never add red arrow on ST or Wingers for its useless and have no effect what so ever just tier the players faster, red arrows on AMC are a blessing in disguise
If we look past formation, full pitch will come with offside trap most of the time and allways Zonal marking(ManonMan is to defensive)
that means your team will pass the half line so red arrows on defenders is a mistake unless your team is rly strong!
