You can ignore other Phoenix and keep gearing Ezra, he's worth it, you can also beat EP event with no problem, do daily activities and get as many exp as you can, you can get some scoundrels for credit heist to buy better mods, your Phoenix should be able to get Thrawn at 6*, and you don't need a really high star level for a good Thrawn. Worse case scenario, Thrawn comes back tmr, you should gear the following: Chopper, Ezra and Hera, Chopper is fast with his dispels, and Hera is squishy and give back up plan, Ezra can be used outside of Phoenix and generally a good attacker, if you want to play safe, gearing them all at gear 9 might be enough (and get Ezra to gear 10), keep on trying until you got the right RNG, 7 days are long.
