Flying makes it a lot harder to design content for the game. I understand why they wanted to remove it.
But I like flying. And I like that they’ve finally added more to flying rather than trying to treat it as a mistake that can only be allowed at the last second. The number of RPGs (MMO or otherwise) in which you have meaningful flying content is very small. I play DF more than most of the other recent expansions because of flying and it’s getting me into caring about endgame again because I enjoy going places.
Sorry but not sorry if you hate flying.
