Each time a teammate gives up in a game...
I just want to be able to link this. Sure the game is radically different from LoL, but the point still stands.
Edit: Forgot to put in the point. It is; Never give up. No matter how far behind you may be, your opposing team can screw it or you can catch up due to them being unable to close out the match, ultimately snatching victory away from them. How so depends on the team's ability to hunker down and stall/turtle. Even if the opposing team scales harder Even that is possible with the current meta.
