I hear what you are saying - But that is a terrible idea.
If someone wishes to pause the game and make tactical changes etc... that is allowed within the boundaries of the game. And sure if you are 4-0 down and your wondering what on earth the opponent is doing. 70mins in the game. They are allowed to make changes or pause or whatever.
Is it annoying if you are losing? Sure. But they are doing nothing wrong. They might be making formation changes or anything in that time window.
What you want to be more worried about is playing International Vs Club Teams. That is a bad idea. Id change the setting that forces only clubs Vs clubs and International Vs international. It's just ridiculous Club Vs country. I hate that.
And one last thing. There really isn't any such thing as putting this game on late at night to have a wind down or chill time. Online is completely competitive and people are only playing to win. And some are playing to win and humiliate. It's just the nature of online gaming. And especially this game. Football in general TBF.
So all in all no. Pauses must remain as they are.
