I also think it is too early to say. there is a huge difference between a prediction and actual practice. some things which may look good while you are staring at cards fall completely apart on the table. the "meta" takes time to evolve, and, like natural selection, tends to shape itself over lots and lots of games. what does not work repeatedly gets phased out, and combinations that are powerful see more and more play. If you can figure all that out in a game with this many possible combinations, then you are beyond genius.
What this seems more like is - here are the broad possibilities. I can run a few big ships, more little ships, lots of fighters, no fighters, or somewhere in between. I think that about covers it, but I'd be hard put to call that any kind of prediction, more like stating the obvious. not trying to be snide, but wave 1 has been out less than 1 week, it's a little early to be talking about a "meta" of any kind at this point.
Yeah, but I think we're largely at odds over terminology.
Darth Ruin, I think, makes a useful contribution by starting the debate and introducing the big question of: Squadrons yes/no/what type? He sets up some ideal-type fleets; fleets that exist at the extreme value of some attribute. Provided that these types of fleets are only suited for some very specific specialization, they should not be the sort of fleets that any wise player would build.
But, as you point out, that's not really what you or I understand as being that elusive thing called "the meta". "The meta", as that term is commonly understood, is what does actually seem to be played, and there are archetypes within that meta.
While there are doubtless communities where a meta (including awareness thereof) does seem to be developing, I don't think it's all that common yet, and with Wave 1 still having that new-ship smell, it is probably too chaotic right now to make any sense of. So, we might as well refer to the realm of possibilities, the way that the OP seems to be doing.
To that point: There's probably a centripetal logic that should force people to make balanced lists, rather than extreme lists. If you're facing a fleet that has no fighters, devise a tactic that makes the maximum use of your bomber/fighter capability. Have your capital ships steer clear of your opponent. If the case seems to be the opposite, lunge in with your capital ships so that the turbolasers do most of the talking before his/her squadrons can gnaw away at your ships too much.
The problem with specialized fleets is that they will not be all that adaptive, whereas balanced fleets should be much more adaptive than the specialized ones.
