When you win a 5v4.
If you are the 5 do not brag, do not pretend you are this god among men. You won with an advantage while the other team fought a good fight and held there own. You should honestly be reported for unsportsmanlike conduct for rubbing it in. Be gracious applaud the other team if they put up a good fight and honor them if they deserve it. Who knows maybe it will be paid forward when its you one man down.
That's all I have to say but apparently some need to hear this.
