I rarely look for counterformations.

I prefer to look at my own team's strength and play 2 to 3 formations, depending.

I favour twin strikers so my formation revolves is built around my twins. Usually I tweak a little, normally only taking into consideration whether the opponent plays an AMC or none. The rest are arrow plays and mentality orders.

My basic formation is the 3-5-2 motivated and I play around with variations. A lot of times lately i've gone 3-1-4-2 which is a variation of a 3-5-2. That's probably because I've encountered a lot of AMCs.

I can pull my DMC to a DC if the opponents AMC is having a quiet game and go 4-4-2 (I play with a DL/DC & DR/DC, so easy to switch). SOmetimes revert to 3-5-2- flat or motivated. I don't play AMCs so I dont quite use 3-4-1-2.

Probably you can say I counter threats instead of formations.
