The thing that I feel was legitimately disrespectful about Ion's answer was basically the same he gave 7 months ago, so he's basically saying that in 7 months no one raised one single point worth addressing in the Q&A about High Elves.
That's just not caring about the community feedback, regardless if you agree with it. But the lack of acknowledgement of it all, of all the ideas people came up with, of all the points raised, is what feels very discouraging as a community, regardless of the answer. (Which really, doesn't surprise me because the faction identity thing alone was reasoning enough from a gameplay perspective)
