So it would be fair to say Carriers are in a good place. Various upgrades and the unique squadrons from Corellian Conflict have all been really good to the archetype. While it's an efficient way to deliver dice on target it's not infallible and it's harder for a carrier group to separate effectively or reorient to meet threats from different angles.
I'd also say the cruiser, i.e. smaller snips, are in a pretty good place. There's a pretty solid array of useful upgrades that allow them to make their presence felt even with less dice (TRC, APTs or ACMs) and their agility can make them at least somewhat durable even if most won't stand up to direct fire very long.
That being said, the Battleship i.e. Large ships and even some of the mediums like the VSD are currently struggling from what I can see. The drawbacks of Battleships are pretty severe. You usually get a fair bit of point bloat, because if you're already investing 120, why not 126 or 130, etc. Even if the upgrades are somewhate necessary, this still inflates their cost pretty substantially. They also only have one pool of defense tokens making them excessively vulnerable to things that mess with defense tokens ala Intel Officers and soon to be Sloane. They also generally have one pretty godly arc and all the others are at best on the firepower of the cruiser making them much easier to dodge (getting to the side of a gladiator doesn't really change the dice and CR90 saves you one red, but getting in the side of an ISD costs him 4 attack dice). But at least for you troubles you get...actually what the hell do you get? The only real bonus is that because all of your points are focused in one place it tends to be all or nothing, but it looks too often to be the 'all' side of that equation.
With the talk about squadrons, I started looking at the ships in Armada after worlds and TBH I didn't come to the conclusion that carriers or cruisers were overpowered, but that battleships were underpowered. Why isn't there an upgrade (or hell, I'd be fine with just a change to the core rules) that says that Large ships don't take damage from rams except by other large ships (or even any ship smaller than itself)? As much as I thought about it, I'd also be fine with adding a line to gunnery teams "If this is equipped on a large ship, it may attack the same target with both attacks". Possibly even a Large ship only upgrade that adds a flak die, which seems like a good compromise as there's a much harder cap on the number large ships than any other size category. There's a massive opportunity cost going into these behemoths, but it feels too much like their just point sinks that make it easier for the other player to get VPs.
Possible I'm just crazy, but I like the big ships and they're so hard to justify now.
