It sounds crazy, I know, but I think Armada may actually allow for more diversity in terms of fighters than X-Wing ever did, if we are talking about roles versus pure stats. Hear me out on this.
In X-Wing, the ships have low diversity in terms of role, because every ship is essentially pigeonholed into a dog-fighting game. Their stats, actions, and upgrades provide a wide degree of ship difference in skin and combat capabilities, but it seems to me that they all remain basically the same thing just made over in different flavors.
A brief example: the lack of truly dedicated bombers. The expensive nature of ordnance in X-Wing has almost removed bombers as a reasonable investment. Thus, we see Y-Wings acting as a mobile turret party rather than in their intended role: as bombers. Also, B-Wings serve as jousters extraordinaire, which is the opposite of their role in much of the lore, where they are bombers needing an escort. TIE bombers shoot off one missile and then dogfight with X-Wings and A-Wings...very non-lore stuff. The role differences in X-Wing are divided into things like turrets and arc-dodgers, which are distinct, but still serve only to increase their value as dog-fighters. For X-Wing, this makes sense, as it is a game all about dog-fighting. But it leaves me feeling that the ships not meant for this role get short-changed in a way.
In this light, Armada will perhaps showcase the different varieties of fighters in a better way than X-Wing ever did (at least in terms of role diversification). Bomber, escort, heavy...all of the keywords provide a natural and interesting role development for each ship. Y-Wings and TIE Bombers become heavy ordnance delivery systems weak in the dog-fighting department, Interceptors and As become fast interceptor craft weak at hitting caps (I hope...not quite sure what their keyword does), and the X-Wing truly shines in its intended role as a jack-of-all-trades, space superiority craft-- escort, toughness, torps, the works. TIE fighters--even more swarmy than in X-Wing, which makes them feel very lore-consistent! The role diversification feels very Star Wars to me.
In sum, though the fighters will not have much statistical variance in Armada compared to X-Wing (that pretty much goes without saying), the role variance has been developed in a way that I find to be very appealing. Give me my fighter-bombers!
Don't get me wrong, I LOVE X-Wing...I am just prepared to love this even more, and not just for the capital ships!
