This is due to the system abuse that we all saw in Season 1 - players of 70+ Skill rating partying up with 20-30 SR players to get easier games and win more often then not. This new feature will certainly limit that system abuse and the games will feel much more balanced.
HCM is the second most common form of cardiomyopathy. If you have HCM, it means that the walls of your heart are thicker than they should be. Some thickening is normal for healthy people who exercise or who play competitive sports. But with HCM, the thickening becomes extreme. In time, the thickening of the heart muscle can cause the heart to get bigger, or enlarge.
Symptoms can include chest pain, dizziness, shortness of breath, or fainting. HCM also can affect the heart's mitral valve, causing blood to leak backward through the valve. Sometimes, the thickened heart muscle doesn't block blood flow out of the left ventricle.This is called non-obstructive hypertrophic cardiomyopathy.The entire ventricle may thicken, or the thickening may happen only at the bottom of the heart. The right ventricle also may be affected.CM is a common cause of sudden cardiac arrest (SCA) in young people, including young athletes. HCM occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. Despite this thickening, the ventricle size often remains normal.
