Just don't actively chase champs. They're already have a terrible match by missing 3 of their team, you don't need to pour salt in the wound. That makes you the biggest sore winner in existence. Just rush towers and end the match as soon as you can instead of dragging out the match by having 1 person push each lane slowly. Group as 5 and finish the game. Some people should look up dignity.
I always try to end matches as soon as I can when the enemy team has a clear disadvantage. One game we had a 5v4 and their level 2 Zed didn't reconnect till around 30 minutes. My team instantly kept trying to get their Mejai's/Occult stacks off of him. I just let him farm in lane with me and warned him if my team was coming for him. My team yelled at me and said "Wtf Annie" but I felt bad since this was normals and I killed him without me knowing he was AFK when I flashed Q Ignited. The game became a 5v5 and was really close but we still won and to tell you the truth I'm glad that happened. My team got way to cocky getting Mejai's and Occult.
You can also try to surprise surrender at 20.
