How to Win Against Any Formation?

So you are saying that where Nordeus advise not to use illegal formations, there are neither penalties or they are misleading everyone just for the hell of it. So we can all forget now about, minimum three defenders, 2 flank players and one striker, not forgetting the keeper.
I've played four illegal formations this season already, 3 away from home and had 78/80% possession, the opponents also seemed to pick more than the usual amount of cards in a game, could have been down to their selection of hard tackling but I'll never know that.

Does this mean that illegal formations are fine to use? The four times you've used illegal formations, what were your possession stats? Do you have screenshots, maybe?
