I was similar to your friend, I stuck to 3-4-1-2 most of the season but on the rare occasion tried to counter my nearest rivals but it didn't always work. The best thing I can suggest is to find one formation that works best for you but always have a good back up plan.
agree. i played 5 season 4-4-2 and ONLY that. now started to mix, play often 4-5-1 V and 3N-1-4-2. I beleive even if it is an algoritam and not a real people, it takes some time for team to adapt on a new formation.

I did that, I won that...blah-blah-blah...
