For some, alignment systems seem less sophisticated but I think that's just a case of it being done well or not.
It's impossible to do right, morality is subjective. I know this is a fantasy game, but the fantasy of morality being objective is not something I am interested in.
I think there's a difference between pleasing everyone and doing something well.
And it's part of the setting and what makes it special. It's what makes Faerun different than Rivelon or whatever PoE world is called. In the realms morality is real. God really do answer prayers daily and your adherence to alignment (mostly) determines your afterlife.
Why do the gods give people power at all? Why give religions different creeds?
And in other settings like Ravenloft alignment matters even more and the Bhaal powers were really stolen from the Ravenloft 'powers check' mechanic. After three evil acts, after gaining three god like powers you lose yourself to evil and become yet another lord of Ravenloft.
