For the Paladin itself I saw the reasons why it has a alignment restriction with the class being representing the champion of a god. But today I found also other classes having alignment restrictions and I'm wondering how strict those are.
As example the shifter from spheres of power with any non-lawful.
For races I know there is the up to 1 alignment shift that is being used. But what about these classes where there is no indication as to why they have this alignment restriction? Does it also count there? or not? And if it counts what in cases like the shifter?
