Why is Champs gameplay so different?

yes! same here, Rivals and Friendlies are butter to play, but the moment i play champs, my players act like they are stuck in quicksand and take 3 business days to shoot to goal, only to get the shot blocked by VVD who btw sprinted his way back from midfield  and caught my player in 0.6 seconds. some people say Champs is the better mode (gameplay wise) but i guess it varies on people
