What should I work on, just hit lvl 60

Al_Jogor

So, I think I'm doing ok in the arena right now, with rank around 30.

But what characters do you guys think I should work on?

This is what I have and currently use:

Darth Sidious*7
Jedi Consular*6 (halfway to *7)
Luminara Unduli*6 (halfway to 7)
CT-5555*4
Darth Vader*4

I also have
Savage Opress*4
Talia*4
Grand Moff Tarkin*4
Poe*4
Chewy*4
Admiral Ackbar*4
Luke*3
FOTP*2

I'm currently working to raise the stars on CT-5555 and Savage Opress and I plan to replace Darth Vader with Savage Opress when he is higher.

So..
Will Sid, JC, Lumi, Fives and Opress be an ok endgame team?
When Lumi is *7 I guess I will start getting Phasma.


Any suggestions on what I should change or aim for is appreciated.

Thanks
