Back on topic....
*Saruman* :
I got done by Bros Boys of Scrumtouchables using MB against me in a tournament. Both L61 he beatbme by 4 points. Played his straight after in a friendly and smashed him 31-0.
Friendly game engine is a piece of cack Saruman. Have you actually checked the wildly varying results you get from it? Bros Boys maybe just adjusted his tactics for your tournament game and then reverted back to other settings to play someone else which, for your friendly, happened to suit your tactics. Don't blame bonus unless you have hard evidence would be my advice.
