The counter for 4-1-2-3 is incorrect. I just played a friend (who happens to be in my league) using 4-1-4-1 to counter his 4-1-2-3 formation. I lost 2-0, I had 5% possesion bonus, I even added blue arrows to the DMC to make him help against my opponents 3 STs, and we are almost exactly the same average quality. Nothing worked.
