Especially because all these rules almost always boil down to "use these terms to mean what I say they mean or I'll get angry at you." Examples:
-
I don't care what you personally believe the difference between a drake, dragon, and wyvern is. In your story they can refer to wingless lizards with four legs, flying lizards with four legs, and flying lizards with two legs respectively, but in this story they're all flying lizards with four legs but drakes are venomous, dragons breathe fire, and Wyverns have an electric eel style shock and that is equally valid.
-
Wizard, Sorcerer, and Warlock do not mean "Mage by training, mage by birth, and mage by pact." They mean those things in Dungeons and Dragons but I will lick Satan's taint before I bow to WOTC on terminology. If you want to use those terms to mean those things, go ahead, but if you um ackshully a random non DND Fantasy story about those terms...why? Why do you want to try and limit someone else's imagination? (also even DnD didn't use those terms until 3rd edition)
Just...let people play with their imaginations, okay?
reminding me of a conversation I saw on discord way back that was just a head on collision of someone talking about "5e" (D&D) and someone else talking about "5e" (Shadowrun) and they were both trying to talk about why wizards are bullshit
