What do you think of this formation?

I don't think focusing on the flanks is necessary against a 3n-2w-2n-1-2. Your opponents formation doesn't present an offensive threat from the flanks and adequately defends them. Your oppositions defensive weakness is he can't focus an attack through the midfield, while defending it at the same time. If the MC's have red arrows, your red arrowed midfielders will be running amok! If the MC's have blue arrows, the offensive threat will consist of long passing over the top, since any form of short passing will just prove stagnant if the midfielders aren't offensive minded. I'd run a 4-1-2-1-2 ND. Since there aren't any illegal formations anymore, a 3n-1-3n-1-2 or 3n-1-3n-3 should work as well.

Attacking, through the middle, whole pitch, hard, short, zonal, no counter, no offsides. Red arrows on all midfielders.
