Are Geonosians worth and other farming questions

Agree with Snowlock -- CLS lead, R2, RHan once you get him Old Ben, +1. I use Thrawn, though Chirrut, Kanan, or GK once unlocked could also fit pretty well. Even STHan or Ezra wouldn't be bad at all while you wait for more synergistic toons. Of course, Wiggs is viable as well, I used them for a long time myself. That team would probably look like CLS lead, Wedge, Biggs, R2, and RHan or OB.
