Seriously I also had problems with the subs too.
On the other hand please:
Explain the position of the players on the field. Is a forward to the limit DR/DL and a ML/MR that plays to the limit in the back basically the same position. Do some of the old formation restrictions still apply.
But most important question? why don't you ever listen. You consider a feedback some kid who rates your game 5 stars and writes BEST GAME EVER after playing it for 2 days and ignore all the people who take time to put elaborate suggestions. If it wasn't for the community this forum would be dead.
It is your choice if you want to put your focus into tricking causal gamers into spending money once or twice until they get bored.
