This change will surely be unpleasant to many people, somebody pointed that GKO engine should keep improving, and i agree with that! However, this change will affect all teams, many teams will need to start over on their player's development, so it won't be an entirely popular change. My team won't be that affected, i play UMR when possible, so my team has decent teamwork rates mostly (i will need to work on my defenders, i don't use offside trap so i haven't worked on it that much).
However, i think that many people will apreciate other changes in the GKO engine, and those changes wouldn't affect our player's development.
Nobody would be angry if:
* Players could receive direct red card, specially against hard tackling teams.
* Corner kicks would happen if the keeper tip the ball away.
* Goals from second chances happen (player A shoots, Keeper saves without holding the ball, player B shots after that keeper intervenction).
* Offside trap would be rebalanced (i am tired to see defenders failing into offside trap).
* Kicking ability should have a clear role in the engine: more ball posession maybe?
* Indirect free kicks, working similar than a corner kick.
Not to menction other things requested, such as a substitute player list.
But well, we have some time to be prepared.
