This is a new rule that Nordeus will implement in time for next season.
Response to question 2 is same as above. Also bear in mind that if the game picks out 11 players to start, most of them will likely be out of position. From what I've read on here, each player that's out if position yields a 5% decrease in possession for that team. Assuming this, you should get more possession that usual and hopefully win the game.
