43N3 can work against vanila 442 because of midfield. Patch that problem and exploit the flank you can make a hard counter against 43N3 with four defenders. For a ridiculous hard counter against it, 4R-0-4L-AMR-ST(L). Yeah, this is too asymmetric.
Those super effective counters against many common formations are asymmetric.
What else did you think how I consistantly beat teams with one star average higher than mine...![]()
