More dragons please? Maybe include a flying citadel or flying sail barge or two? Just some ideas to play with.
Won't there be one more dragon? ( though i heard that the dragon from AoI may make another appearance, but not until Shadow is over and Ice has begum)
Personally, I think dragons should all be given the flying promotion.
Flying ships could be cool, perhaps as heroes available to anyone at astronomy, or by random events, or perhaps as an national unit upgrade of the Arcane Barge available at Strength of Will (wind I-III and fire II,III sorcery spells would make these quite useful)
Yep, looks way more meaner and more serious, which is how it's supposed to look.
