Having better defending mechanics and reducing the Set Pieces goals will help bring back some balance. I concede at least 1 goal every 2 games from a defensive throw in one-two (an acknowledged bug SI is working on), usually my opponent's first and sometimes only shot on target.
I also just conceded a goal because my defender chested the ball down undisturbed in the 6 yard box, but decided to stare at it for 3 seconds, the GK didn't move and a striker ran to the ball and scored. I was 7-0 up after scoring 4 set piece goals and it was their first and only shot during the game.
Agreed re match engine. It is looking great and more responsive to tactical changes than the past. Although I agree with RDF, something's not right with pressing/tackling and wingbacks running the whole pitch undisturbed.
