I've had more matches holding 60-70 percent possession than 70-80 this season, but that could be many factors.
I do play attack arrows on either or both out of position midfield players, no problems it seems,a few yellows for MR. The only time I played my very attacking balanced AMC as MC with attack arrow he got 2 yellows in one match, very, very rarely picks up fouls in AMC position.
