One thing I could not help but notice in the Armada demo is that both X-Wing cards out, Luke Skywalker and the regular X-Wing Squadron, have an ability called Escort . The actual text is:
" Escort. (Squadrons you are engaged with cannot attack squadrons without ESCORT .)"
This is a fantastic addition to the game, in a genre where it is important to design every element in your fleet with a specific purpose in mind. In a game of Epic X-Wing, you can field a wing of Bombers with torpedos and simply fly over to your opponent's capital ship as quickly as turn 2 without them being able to stop you short of diverting their whole squad's attention to it.
In Armada, it seems like the rules are directly facilitating purpose-built anti-capital ship bomber wings. Assuming there will be Y-Wings or B-Wings, which roll more dice against capital ships, then you'll be able to protect them with Escort ships. Attacking ships will have to chew through your Escort fighters before being able to destroy your bombers. So it prevents your specialist ships from being sniped immediately. However, due to the engaged rules, it's still beneficial to harry your opponents' bombers, because they can't fly off and attack your capital ships while engaged.
It also allows for some named characters, like Vader perhaps (Leading Black Squadron?), to be protected by other squadrons with Escort. Very Thematic and appropriate.
All in all, I think it's a very elegant way to handle this system in a game where you're job is to micromanage capital ships - you just give your commands to the fighters, and they automatically do their thing of engaging and locking down enemies. Meaning, they're important, but the focus is still on the big ships.
What interests me is that the base games doesn't appear to have any Rebel squadrons without Escort. The preview said the box only comes with TIEs and X-Wings, so this mechanic may not come into play with the starter at all. We may be able to infer from this that the Armada special announcement (X-Wing has it's own) on Friday will be for Armada Wave 1, with new squadron types like Y-Wings and TIE Bombers. Otherwise, unless the starter has more cards than it seems, they'd be releasing a game with a mechanic that doesn't get used.
