Just thinking out loud here:
I like Armada as much, if not more, for the thematic reasons/minis as the game itself- it just so happens, that, unlike some other games that shall not be mentioned, the game system is deep enough to allow me to craft pretty much whatever list I should so desire if I play it right. I may not be able to 9-2 at a tournament, but I won't auto-lose every friendly game (which I consider a huuuuuge distinction).
Now, that being said, when I want to roll out my rebs, my thematic fleet might be considered "good"- multiple small units, flotillas, lots of fighters and bombers doing what they do best. Sometimes there might be an MC cruiser of some sort tossed in there, sometimes a neb-b (or even two!). And it doesn't take much work before it looks like the fleet at Scarif or Endor.
But when I roll out my imps, my thematic fleet might be considered "bad" because it's essentially a big pile of star destroyers and tie/ln. Thinking more about this, though, I think I don't have a "large ships suck" problem as much as a "deployment is really, really, really important and unforgiving with fewer ships" problem.
I've been trying to, in Vassal and on my tabletop, view the game more as a 4D problem (or 2D + time if you want to be snarky)- there are only six turns, and six maneuvers any given ship can make, even less once obstacles are factored in. That means a lot of the game happens before turn 1 on deployment of both ships and obstacles. Being "out-activated" is another way of saying my ships cannot react well. There is proportionally more of the game state I give away per turn before my opponent does when I have activation disadvantage. I have lost the initiative (not the literal game initiative- talking about the ability to set the pace of the game). Am I therefore automatically going to lose? Well, no- I have a particular advantage in large ships. The way maneuver works in Armada, outside of some really, really incredible flying (and some obvious telegraphing of intentions), there is no way to match the economy of mass (that is l ocally having "the mostest" in any given part of the battle) of a larger, decked out ship. Two neb-b's have more firepower than one ISD-II out the front at long range, but getting those guns to bear at the same time is a lot harder!
So what can I do with that? I need to make sure that I'm not depending on "fudging around" to adjust my game state to where I want it to be if I am going to come with large ships. I need to focus on preventing disadvantageous future game states via deployment and intentional maneuver. If I'm getting shoot-scooted by CR90's all day long, then I have a deployment problem- yes, it's true that if I'm out-activated, I probably have to move that ISD into range first. But if I know this before hand, why isn't it the case that I force that "safe flank" of my ISD to be covered by another ISD or Arquittens? I need to think about how to remove or minimize those safe spaces, including the fact that every time I activate a ship that perimeter is going to change a bit.
No real firm conclusions here, again, just wanted to hopefully spark a productive, rather than inflammatory, conversation
