Shoot for cardboard cutouts?
The characters exist only to move the story forward?
Nuanced fantasy won't read "true"?
Wow, Steven... You've said that fantasy isn't really your thing, and if you think that's what most fantasy is (or, gods forbid, is supposed to be), I'm not surprised you don't like it much.
Your advice is usually good. Some of it in here is too (the part about the setting being a character, in particular, is gold). But, with some of this, you're not telling people how to write a fantasy story, you're telling people how to write a bad, cliched, caricature of a fantasy story.
Yes, there are a lot of fantasy stories with cardboard cutout characters and no nuance. Just like in most other genre's, there are too many. But that doesn't mean it's a good idea to emulate them. Fantasy is no different than any other genre. The character types and other tropes should only be a starting point to go somewhere new (and, hopefully, better). Otherwise there's no point in bothering.
