I just played vs this arrow formation and beat it 6-1 with 4-5-1V. This 6th place team(30Q) beat the 2nd place team(32Q) that was playing a 3-5-2 down the left flank, watched the game and got 55% of possession, made 3 subs at 55' and still got jack squat vs this arrow formation.
There is something to be said for countering. If this guy knew that 4-5-1V beats this formation, he might have changed his formation. He played me with that same 3-5-2 left flank formation and lost 1-0 a few games ago. If it works for him, fine, but now he was beaten twice and drawn once in the past 3 matches.
But that is besides the point. There are some strange results and I dont think you can just let your team ride the same formation game after game anymore.
