If we are talking rock-paper-scissors, the usual cycle I see is this:
No squadrons > Fighters > Bombers > No squadrons
For instance, if you are in a meta where people are taking lots of imperial ships without fighters, I would suggest the following list as a thought experiment:
AF MKII B - Dodonna, Adar Tallon
Neb B Escort - Raymus, Yavaris
CR90A (with or without Leia, depending on how you feel about your bid)
Keyan Farlander, Luke Skywalker, 3x B-Wings
Running ships with no fighter support into close/medium range at this list is an experience roughly akin to sticking one's junk in a hornet's nest and thrusting vigorously. If you arrange your fighter screen so that your opponent has to bumble through it to get to your ships (especially Yavaris, don't let that die early), depending on setup they are eating somewhere between 6 black dice + 3 blue dice to 10 black dice + 5 blue dice in a single turn from just your bombers. You also have ships to fire!
Did I mention every single one of those ships also has bomber, so they crit with Dodonna, and some have re-rolls or the ability to ignore shields (which I have not factored in)?
For those running in metas where people think no squadrons are a smart thing to do, I suggest this kind of counter-list until people learn there is a reason to bring a balanced list.
