"We believe our lower ranks have a few too many of you, especially Bronze and Silver. When we were looking at rank distribution, we realized that if we were to move some of you up and out of those lower ranks, it would overpopulate Platinum and Diamond. So by adding a new rank we can better distribute you across ranks, keep the prestige of high ranks, while helping better define the skill level of each rank."
