Capital Ship strength

Tarkin, Ackbar, and Thrawn have faction synergy built in to their capital ships that Mace doesn't really have because there are so few good Galactic Republic ships. The old ship meta was an Empire target lock team with Biggs because there aren't any good Empire tanks. But now, the best tanks in the game aside from Biggs do not match with any capital ship. Hounds Tooth & Sun Fac can be paired with any capital ship to good effect. Light side and dark side are not generally important to fleets unless you're running Han's Falcon. The only time they come into play is when you're upgrading capital ships.
