Best Zeta for My Roster

Hi I run a full FO team with zetas on phasma, FOST and kylo. You have been given solid advice and while you're building a FO team, kylo should be first Zeta. FOST could be a second Zeta if your team isn't ready as his Zeta is great but he's hard to farm.

FOO ironically doesn't have a Zeta but is key to a functioning FO team so stick with it!
