As advertised earlier, there are new supplements coming for Armada introducing flyers and more magic. See the fresh posts on the Mantic blog: about the Seas Aflame supplement book, and about wizards and magic cards.
I am looking forward for the flyers, apparently each fleet/faction will get two of them, for the rules on fortifications and especially for the campaign rules (I really enjoyed playing a Vanguard campaign). However, I have a mixed feelings about the newly itroduced magic rules. I would not mind a few more spells and adding wizards on the board of the ships. However, 50 spells for general use and additional faction specific ones looks far too many for my taste.
