Let's see. I would split up your Jedi like this:
- Bastila, GMY, HYoda(try and gear him to around 7 so he doesn't get one shot by an AoE. Plus he'll be great once you get JKR)
- Ezra, Jolee, Old Ben
That gives you 2 solid teams. Now here's some other teams:
- Hera, Zeb, Chopper/Kanan
- GBA, Spy, Sun Fac
- Padme, Ahsoka, R2(could put Luminara here, or even GMY if possible.)
- EP, Thrawn, Vader
- Bossk, Jango, Boba
- MTalzin, NS Zombie, Ventress, Daka
- Nute, Dooku, Grievous/Geo Soldier
Hopefully that helps you out. Good luck this season of GAC!:)
