Even so, I would perter to not delve into third party materials beyond specific exceptions. Referencing third party books for things such as say, favor class bonuses for races who don't have them specified, sure. Bits and pieces maybe. But I'm calling the limit on third party classes. Have enough of a headache learning about Paizo classes, especially the ones that are legitimately more powerful than third party materials. I would rather not have to wrap my head around third party stuff which aren't exactly any easier. For the sake of conveniences.
