I see a lot of successfull managers playing with 3W formations ;/ I feel this kind of formation should suffer a lot of goals.

And since this new version (with that matchup view), it looks like it's favourable to formations that have 1 player in every place of the field. Like that " DL DC DR, DMC, ML, MC, MR, AMC, ST, ST" that is being really hard to beat. In the match up view, you can put many of your players anywhere, but the zone of the field will never look favourable to you (with that bright color) because your opponent has players everywhere
