I just read this on the FFG News about Star Wars Armada
While you are not required to field any squadrons in your fleet, the squadrons that you bring to battle can easily prove the difference between victory and defeat.It’s hard for capital ships to hit them because most capital ships’ anti-squadron armaments number only one or two dice. Meanwhile, your squadrons each get their own attacks, and your opponent’s ships only get a limited number of defense tokens each round; swarms of starfighters can quickly wear down even the largest of ships.
I didn't mind that Epic ships could die by focused fighter fire but now it makes even more sense.
