So I'm averaging 21 in the arena with my Rebel team. I finished G11 my relevant Rebel team and upgrading my Ig88 and Ig86. I am currently trying to improve my JE and Nebit so I can further improve my contributions in our tank raid. I have side farms along with this and I can't seem to focus should I:

1. B2 - currently only at 4* gear VIII but can be highly valuable even in GW. Will be a good mix since Im improving my droid team.
2. TFP - 7* and gear VIII - can be used to mix things up and improve the performance of his ship.
3. Bobba fett - 7* and IX - can be mixed with anyone
4. Aayla - Can greatly improved my team C (jedis)

Other option: Barris (zetable?), Vader (zetable?), EP (Useful but stuck at gear X), Phasma (stuck at gear X as well but proven to be useful for raids and GW), Fives (Zerable)

OK TLDR, but at the end of the day, what do you think are the must haves right now? And since Im about to get 20 pieces of zeta materials, who can I use it to as a main project?
