Druids and Clerics should be the same. But DnD was invented in the 1970s, when the unwashed druggie movement was still quite popular. And thus various hippie silliness is hardwired into the setting.
BTW - Bard started off as subclass of Druid - the musical backup to shamanistic rites - hence the odd mix of Divine and Arcane spells.
that... makes so much sense actually.
Spells are just like weapons: they don't have alignments.
i only suggested an alignment system because each deity granting its own spell list wouldn't be feasible.
but explain to me, how does the goddess of darkness, loss, deception and night, have the ability to grant people the power to shape and command light? or heal wounds? it literally doesn't make any sense. it's not in her powers. this isn't the abrahamitic god we're talking about, who's omnipotent, the gods in dnd are more like the greek gods. they are fallible, can die, each have their own skills and abilities and personalities. shar simply does not possess the authority to give someone the power to control light.
