I really want to give my fullbacks attacking mentality, but my league is so tight at the moment, I dare not take a risk. So here's hoping someone else will carry the burden of testing it out over a stretch of games.
Or having Marcelo in Real M. , give attack arrow and he 'll play as a winger. But don't expect from him to contribute much in defense.
So you cannot have the same tactics for every game.

I remember the old times ther were many conversations about "imaginary" game scenes as effect of the arrows.
Forget about it.
it just % numbers.
