This is not a complaint… I will probably never even use the Atlanta troop.
I was probably playing Gems of War before it was even made available to the public in the XBox Store in 2015. So I think it’s highly unusual that I only have 2 Atlanta cards… when most of my other cards (including most common cards) are becoming Mythic. Even more unusual since Atlanta is a version 220.127.116.11 card. I have many cards that were just released a few months ago that are already fully Mythic.
From a mathematics perspective… as the set (number of cards) becomes larger there will be unusual edge cases that are within standard deviation… such as cards not appearing even after many thousands of iterations.
I think the dev team should start considering a weighted distribution on older common/epic/rare cards based on either release date or version number.
