there are lots of people complaining about this bigb79, its scattered all over the forum. its not so much the game engine changes, its the fact that now the game engine has rendered formation, tactics, team quality, ect ect completely useless. you get better results by not attending your games and by playing unusual formations for example:

st-st-st
_-_amc-_-amr
_-mc-mc-_
dl-dc-dc-_
