... are you going to be so deliberately obtuse as to try to pretend that the role of European mythology in Changeling is the same as the way Exalted rejects it? Because that's just wilful.
Read the goddamn "Sources and Inspirations" section of Changeling: the Lost. What's in it? Oh look it's all eurofae stuff, there's Jonathan Strange and Mr Norrel, and the art and even the front cover deliberately invokes European fairytales. Changeling is fundamentally at its heart about being as fairytale as shit about things and I like it for that. Exalted is not.
And I bluntly care as much about "I can't work with iron nails without a lot of precautions because I'm a fairy" as I do about "I can't be a silversmith without a lot of precautions because I'm a werewolf" and "I can't be a pyrotechnician without all the precautions because I'm a vampire".
They've also deliberately spent quite a bit of the gameline expanding it with, "No, seriously, any and all myths from around the world may apply."
I mean, I'm also just going to say that none of what you're saying sounds whatsoever interesting and engaging, and that's sorta my ultimate critique, personally, since, you know, I'm thinking about what interests me. It doesn't seem to create any implications for fun play that didn't already exist, and it's far too on the nose and simple a weakness to really be all that narratively interesting except in smallish doses.
Like, if you want an excuse to make Changelings act weird and different than other people: Contracts. That's literally the entire point of all of those silly Catches in Contracts.
To make it so that a Changeling pumps their fists in the air when they hear that barefoot jogging is in fashion because that way the fact that they jog barefoot in order to store up a Catch for Never Tread no longer looks quite as weird.
Most of the Catches are meant to encourage players, and thus characters, to be weird in far more varied and interesting ways than 'Oh, I don't touch nails.'
I mean, if you think they don't go far enough in doing so, that's something worthy of discussion, sure.
Example: The Catch for Primordial Voice, which lets you talk to elements, involves spending several minutes making an offering. Changing the lights just right so that the shadows are larger, singing into the open air, sweeping the flagstones...several minutes of it. And if they also *talk* to the element while they're doing it, but before they even have started the magic, that gets a +1 to the dice roll.
At which point you realize that you've had a Changeling spend three minutes talking to a tree and lovingly pruning a bush, and that people are probably staring at the Changeling like they're a goddamn freak.
