At first I thought I liked this rephrasing, so I was going to post my own answer to it (at least the second part). But in trying to think about what I was going to say I read more closely “What do you think of the dominance of D&D fantasy elements in what sometimes feels like every bloody fantasy RPG setting under the sun?”. I’m not sure that the fantasy elements of D&D are what I have problems with, D&D is mostly just a grab-bag mishmash of fantasy stuff. It’s the D&D-ism of D&D where I find the dominance to be a problem, and the way it warps perception of the fantasy genre (e.g. people seem to think that “zero to hero” is a thing in Epic Fantasy because it’s a thing in D&D, even though I’d have a really hard time mapping Frodo’s arc in LOTR to zero-to-hero).
