After unlocking Padme, and being capable of earning Wat Tambor shards in the Geonosian Might TB, your next focus should be on unlocking C-3PO. Goldenrod fits very well into multiple squads, be they Rebels, Ewoks, Galactic Republic, or Resistance. His versatility and massive roster synergy make him extremely important to unlock and gear as early as possible.

His event is also among the more challenging, so Gear 11 as indicated below is the minimum I recommend attempting with. It CAN be done with less, but it's not worth the headache.

Chief Chirpa - Gear 11
Logray - Gear 11
Paploo - Gear 11
Wicket - Gear 11
Ewok Elder - Gear 11
