I also really like DR but it justfeels overly long, not necessarily in length but moreso in content. It feels that there's maybe one too many bosses and the chess piece fight feels like it's less a boss and more just a drawn out tutorial for when you see the pieces later. It could/should have been condensed. Toss the fire breath boss and maybe just incorporate the chess pieces somewhere else, either as a quick sub phase before queen or even as a CE/Skirmish in Bozja.
