"Are you sure you wish to exit?"

I just lost 10 ELO because I accidentally closed my client during a ranked queue (fail). Can we please get an "Are you sure you wish to exit?" button after attempting to close the client WHEN TABBED OUT. I'm aware there is one for when you hit the 'X' at the top right. I was closing game booster though and clicked my league client. I right-clicked the lol client and accidentally exited the client, which is absolutely not worth at all, and it's really upset to be accidentally quitted. Or else, it would be better if I am able to log in to the champ select screen until when the countdown ends
