Best character to farm in each store (lower levels mostly)

Fleet shipments
Best to farm should include:
Ezra. He is one of the top Jedi (not quite as good as QGJ, but a worthwhile addition to jedi team, one of the only phoenix characters worth using outside phoneix squad). Needed for thrawn. More generally useful than D. Maul.

Tie fighter pilot - very good ship, good for getting R2D2, essential for Pit (until you have CLS), good in AAT phase 3, good on empire teams.

Decent to farm: FO Tie Pilot (worthwhile ship, need for BB8, but not a lot of use otherwise)
