Oh really? Then maybe you shouldn't try to steal my idea. I'm not trying to compete, but it was my idea, and the proof is above that you said my idea was not what you meant. I don't think you'd be happy if you found the cure for cancer and someone stole it from you. That'd be a bigger case, of course.
Your idea was solely for a formation change at halftime, with hardly any further elaboration.
I proposed a change to the current automatic substitutions feature for injuries and red cards. I then went on to introduce planned substitutions, preferably sometime after the second half since substitutions hardly ever happen in the first half as a tactical change. These planned substitutions would allow the manager to change the team's formation and players on the pitch according to different situations, whether he wants to chase the 3 points if it's currently a draw or worse, or to tighten up at the back to hold on to a lead.
Anyway, I just hope the devs see these suggestions to improve the game. Thanks.
