Using the "Pillar" farming guide, how do I catch up in Fleet Battles?

A mistake I made was farming Jedi Consular’s starfighter, Clone Sergeant’s ARC-170, and Resistance pilot’s X-Wing to 4* just because I had them. Instead, I should have focused on the ships I want in endgame and what’s needed to get them. Also, keep in mind that your fleet power can jump by 20,000 points when you unlock a good ship.
