I have maintained a 20+ KDA over those 400 games, ending most games with top hero and tower damage IN THE GAME (not just team)
0 times has the enemy had even a 0/x/0 their worst are usually 20/5/12 because even when I go 40/0/0 in a 1v11 I'm killing their whole team not one guy 30 times.
But my rank goes down still.
