i would like to add this,
you cant be too sure what will happen during the game, if your afraid that the defensive strategy you made could be wrong during the game then probably there is somewhere we can improve.
true having an option to change during the game is something good, but your opponent on the other hand set up his offesive strategy only once and you set your defensive strategy only once.
now if it was implemented you have many or lets say 2 boxes for other options you just completely ruined the game and the fun of playing this game.
lets say you have an option to check another 2 options of what kind of defense if he plays what kind of offense shouldnt the offensive strategy also have this kind of option since he cant seem to get his offense going then he should change tactic also. in the end you just gave yourself . . . . . .
itslike your playing tic tac toe now instead of relying on what strenght your team is and exploiting his weaknesses your giving yourself so much assurance to make that game go your way.
all im saying is, and im not bragging. just do a little scouting on what kind of offense his team is playing, then check the team stats and the roster here you can already have a picture what your opponent is.
even if he played a different offense and its not his strenght most likely the GE will still adjust his game but if your ready for his team then you wont just give him the game youll give it 100%
there is no such thing as the most effective defense for inside play is 2-3 and also outisde offense can be won by 1-3-1 or 3-2 100%.
also even if you have the most effective strategy , breaks of the game will hurt you such as injury or fouls
just work on your team what is his strenght, i know its not easy as i have to spend a lot of time here devicing a strategy and even shuffling players out of position.
