I agree with the overpowered stuff, and I am guilty as the next man. We started out Athkatla "1" as above the original SoA level cap, so I was a 23rd level assassin before ever encountering the Time of Demons in the first story. When you start out that high, overpowered is just a way of life.
I'm glad we're headed back to lower-level adventuring. It should give us a better variety of foes (not just demons) and will allow us to concentrate less on abilities and more on personalities.
