LF Help Rounding Out My LS Battles Team

Andrico

My current LS roster:

7* - Luminara (60)
5* - JC (60), Fives (60)
4* - Ahsoka (52), Lando (52), Chewie (50), Rey, Mace, Finn
3* - Luke (41), Jawa (40), Hoth Rebel Scout (40), Ewok Scout (40), Clone Sgt (40), Resistance Pilot, QGJ, Poe, Plo Koon, Lobot, Kit Fisto, Ewok Elder
2* - Teebo, Leia, Resistance Trooper, Jedi Knight Guardian
1* - Coruscant Underworld Police

I'm currently spending my resources as follows:
GW shipments: Phasma (12/85) (Arena leader)
Arena shipments: Sid (90/100) (Alternate arena leader)
Cantina shipments: Fives (45/85) (Arena staple)
Cantina energy: Kylo (69/85) (Arena staple)
Hard modes for the daily: Dooku (5/65) (Thinking about giving up with Lumi and Sid in the bag)

Bonus question: Who's next for Arena shipments? I already own IG-88 (0/30), Asajj (20/30), Greedo (17/30), and CUP (13/15), FWIW.

Thanks!
