It depends on your opponent's tactic, 1 tactic works well against some opponents and useless against another.
I think you need more AML/AMC/AMR and some great ST. Why? Because you could change tactic to 3-2-2-2-1 Butterfly(attack through the flanks) or 3-2(DML/DMR)-2-1-2(attack through the middle). You'll have more winning chances against different opponents.
With your 3n-2(DML/DMR)-3n-2 tactic, orders must be Attacking/ Mix passing/ Normal Tackling/ Own Half/ Zone Press/ Mix passing/ No counter/ No offside. Remember to buy some great form ST.
