Sets

Why does EA close sets 7 days after they open. They make us grind 6 weeks for the season 3 content and then close all the sets 7 days after it even unlocks. Doesn't cost anything to keep sets open. Such a bad player experience. You are just left with useless collectibles sitting in your binder, can't even quick sell for coins. I can't tell if it's incompetence or just lack of common sense.
