You are not alone in your dissatisfaction. I played AST since mid-Heavensward. It was the third job I leveled to 60, and I loved every minute of it. In Stormblood, I played it more than I played my main job (BRD). The card system was a major thing that drew me to it, and with it being changed so much in Shadowbringers, I simply don’t enjoy the job as much as I used to.
