About half of the games I've played in the beta have had numerous amounts of yellow cards (on average I'm having games with 6-9 yellow cards a game, with a whopping 11 alone against Bayern) when the tendency of yellow cards especially in IRL matches don't normally exceed 4 to 5 at most 6-7 a game.

On top of this, handballs can be a given yellow, however I've noticed that even in the 50/50 aerial duels outside the box I've seen players be given yellows, when 90% of the time, 50/50 challenges in the air with a handball never results in a yellow card unless it was intentional.
