Tell me more then if you think it is weak these days.
I think it might be even stronger than it was when I playing the game some years ago. From my experience, 4-4-2 and 4-5-1V seemed stronger as before I could almost guarantee a win if I played a certain way against those. Wingbacks were probably nerfed with the removal of DMR/L, but they were very useful back then against certain formations such as those two. I will also add that the game was clearly biased towards narrow formations where it was favoring them and those that spammed the middle with many players, but these days I have a feeling they are not so favoured - things seem more realistic.
