I've said this on similar previous topics, but to reiterate:
Dragons are supposed to be awesome! Why can't they attack ground troops? And their flaming breath should be able to set scenery on fire, and those fires should spread in a logical fashion. Drakan ('Order of the Flame') managed to implement these features nearly a decade ago, which led to some very intersting game-play strategies. DKS is the closest game I've played to 'Drakan' since, but it seemed to miss the best parts of Drakan's dragon-based combat.
Don't get me wrong, I love 'DKS', but there's always room for improvement. And the fact that my dragon form was always weaker than my human from was a constant source of annoyance...
