Early Adopter: Honor Great Icons

I just recently noticed I have all 5 of the "Honor Great Icons"

Honor Great Leader / Honor Great Mentor / Honor Great Teammate / Honor Honorable Opponent / Honor for All

As I hover over it says "Earned by being in the top 10% of your region in this category"

I am finding this to be quite suspect ... I doubt I was in the top 10% of the NA region for all of the honor great icons... Can anyone confirm if these were truly given out only to the top 10%?
