Teamwork OP

This is pretty old, having come out in 2013, but it's no less relevant today.

• From a 54% avg winrate, having 3 toxic people on your team decreases that winrate to 46%
• Players with a history of toxicty win 35% less games than average.
• Players with a history of positive behavior win 10% more games than average.
