Another thing I don't like is the schizoid nature of worldbuilding when it comes to the standard classes. They're a weird hodgepodge of influences, ranging from fantasy fiction to pop anthropology to self-referential D&Disms, that don't fit well together at all. In throwing all fantasy fiction into a blender, the result ends up satisfying no setting at all.
E.g. the clerics, druids, and warlocks seems to have roots in medieval Christianity and the Arthurian mythos, but then needlessly convolutes itself by trying to bolt on Roman paganism and post-Christian fairy lore without understanding how any of that worked. So both druids and warlocks have fairy connections that don't work at all the same way. And that's before taking into account any other classes. EDIT: Also, the three classes are eurocentric af and display a piss poor understanding of real world theologies, particularly non-European ones. (Long story short, there isn't really much of a difference. Druidism is an Indo-European religion that shares the same roots as Norse and Greek religion.)
Most published settings don't even take into account the D&Disms. Some settings like Eberron or Scarred Lands try to specifically worldbuild around the D&Disms to produce coherent settings. Unfortunately, they never got particularly popular.
Maybe I'm just overthinking it. What do you think?
