Ban all illegal formations please!

Hi,

I just wanted to say: Ban all illegal formations please.
Everyone keeps saying: "If your opponent has an illegal formation, they get ~20% ball possession".
But that's bullsh*t. I lose almost every time.

I'm fed up with all the illegal formations. And probably other players too.

Thank you.

weel, not for me!
when i face an opponent wich uses illegal formation, i always got 80% ball possession and win the game easily..
