Honestly I had way more fun in diadem than I did in PotD.
And in Diadem I worked my butt off to get pegasus and you could get armor that was good and relevant. It was way more interactive and fun (at least for me). PotD has been boring and being forced to do floors 1-20 again and again when your arm and armor are at 21 or up is messed up. Like just let me pick the floors that allow me to improve my arm and armor. Don't waste my time
