Hey Max, I actually saw you quote the PHB entry for Enchantment earlier (quoted above) but then saw you include "magic item enhancement" in your later description. I'm curious why you include that.
I ask because I think so many people can't agree on what the schools are supposed to represent because of the evolving multi-edition history of magic schools in D&D (Enchantment and healing among them), and individual personal preferences based on other IPs ((I remember a Dragon Age: Origins quote from a magic item crafter... "EnCHANTment!), and colloquial use in myths and legends to refer to magic items as "enchanted" to mean "magical."
I feel like when a person's preferences don't mirror the official design in the current edition, it no longer serves a purpose for them, is discordant to them, and is therefore no longer valuable to include in design.
