Badges and the points to earn them
April 2018 was the last time I earned a badge. Your algorithm only lowers my total points needed each week by, I think, 20 points. I can’t play as much as I could in April, therefore I can’t earn badges and coins.
Wake up!! It could be more fun if only you would lower the required points by say, 50 each week until finally I would begin earning them again.
