I've noticed a high amount of my losses are because of this scenario
In my last game, my adc made some questionable plays and died a few times before the 10 minute mark, giving the enemy adc a lead.
Our top lane, started to argue with our adc and say how bad they are.
This conversation lasted 7-8 minutes.
Do you know what happens when you constantly type instead of play? Even if it's between csing and fights?
You lose your game sense, and you lose focus.
We lost because of the excessive typing that went on, we were actually even in gold at one point, and stole a baron, but they kept talking.
Most losses I see are like this, too much typing, and arguments. So, you know what wins games?
Less typing, more pinging.
