Who to zeta first? — For arena ( 4 Questions)

komji15

I’m ready for Rey’s Hero’s Journey.
I almost collect all gears to upgrade JTR to G12. And I will try to make JTR squad with R2(251) BB(276) GK(178 w/ prot. 90000) and Thrawn(238 w/ above 100% tenacity). Yes, it’s a common JTR squad.
(Please don’t say about Thrawn’s speed, I knew it’s not enough. That’s why I’m trying to upgrade mods by slicing...@.@ )

My current arena squad consists of zKRU(201) FOO(226) FOE(184) zCLS(239) Thrawn(238) and recent average arena rank is about 50.

By the way, I have only 9 zetas with 40+ zeta mats: Asajj(U), Bastila, BB-8(Roll), CLS(Binds), Han Solo, Palp(L), KRU(L), Kylo, R2(Number).

Question 1.
JTR squad mentioned above is much better than my current arena team?

Question 2.
If so, give some advice about sequences to upgrade zeta abilities.
(please advice sequences among R2(Combat), JTR(Uniques) and BB(Self). I already know JTR(L) must be first.)

Question 3.
Are JTR(Virtuous) and BB(Self) zetas really valuable?
<If not, I want to invest my zeta mats. for TW>

Question 4.
Facing Palp(L, w/ Traya) or Bastila(L) squad in arena with JTR squad, what is the strategies and killing order?


Thanks for reading my questions.
