I think it just would've helped if FE Warriors released at least 3 weeks before Odyssey. Also, a lot of the reason it didn't pick up as much is because of the roster. It was bad timing and a robust roster choice, but I agree it is otherwise better than Hyrule Warriors.
Echoes would have definitely benefited from a Switch release, it still sold well though. Personally though, I would have rather seen a Path of Radiance and Radiant Dawn dual pack for the Switch.
