Yeah, I prioritize the game-changing zetas, and Finn is probably the single best zeta in the game. My experience with Zylo makes me unwilling to zeta Savage - others are just so much more worth it. On the other hand, because of how good Resistance can be when they deny turns to the enemy, dropping a zeta on Rey for the impossible-to-resist Daze becomes very attractive against enemies that use passive TM gain (CLS, HAAT's B2s or just B2s in general, but I only fight them in AAT, Savage, etc.) or counter-attacks so that the enemy can be denied the opportunity to act completely, instead of just mostly. Getting Poe stunned by Dooku when Dooku resists a stun can be annoying ... sometimes even victory-threatening.
So I certainly prioritize the zetas that will affect an entire faction/squad nowadays, but I'm not refusing to do individual-only zetas like Rey's or CLS.
That helps make the massive expansion in zetas more manageable, but even I am still falling farther behind just in zetas I take as seriously important - Mother Talzin being the latest that has the power to completely change the power of an entire faction.
FYI: I have only 3 zetas: Kylo (which I regret, though I might not if I didn't have CLS), CLS (IBAT only), and Finn. Finn was the best of the three.
