I allready changed to 4-3n-2w-1 cause AMC played bad probably because my tactic was very defensive. I change tactic all the time because nordeus change their game engine after every update. Dont use any arrows (they dont work) just watch how your players are standing on the field (in a game) and move them down or up field. Lately I move my defence and MC's close to my GK as possible, and counter attack with AML-ST-AMR (dont move them).
I have problem with 4-3w-1-2, 4-4-2, 5-2-2-1. I am thinking that against those you should play with ML-MR and 2 ST.
