When playing this game, you must accept that no matter how good your team is, or how good you think you are tactically and all of this, there will be games where luck is not on your side and no matter what you do you will lose these games.
You just have to move on, if the troll result happens to you, it will happen to your opponent eventually as well and on another day you will benefit from it.
It happens to all of us from time to time. One must accept, that we cannot master the game and win every match. We can master certain aspects and win many matches, others who don't know the game as well as we would not win, but not every game.
It's like that and we have to accept it or quit the game if it is not a fun experience overall and play another game.
