Not every spell should have a mirror version, imo. Otherwise we’ll run into the same issue of holy and occult just being bland recolours

When it comes to other spell trees I agree but when Holy and Occult are involved I think it's fine. When that's exactly what the lore says they are...Their opposites of the same spectrum having similarities in these two trees. It doesn't really seem like a bad idea seeing as the lore supports it. But that's just my take on it. 

Light vs Dark Good vs Evil is a mirror that will always be a theme in any medium. But that being said if there are ways to make them different and more unique to each other without making one stronger I'm all for that too.
