Just last week I was playing on Junkertown and we had a Genji that was getting destroyed by the enemy Winston and overall just feeding and giving them all ult charge. He went on a 3 minute rant and eventually just quit when we failed to defend. When it became 5v6 and we attacked, we completely rolled the enemy and only one of us died because of a solo ult. Next round when we defended we were holding them so bad we had them stuck in spawn and 4 of them quit. Sometimes losing that dead weight works wonders.
