What to do with my team

Daxxel

My team is:
JC level 58 gear VII 4*
Dooku level 58 gear VII 4*
Luminara level 58 gear VII 7*
Darth Sid level 58 gear VII 4*
Chewbacca level 58 gear VI 6*

I also have Poe level 58 gear VI 3*

Which character I should get for my team?

Finish Sid. Go Phasma if you want QGJ or FOO. Go Poggle and Poe if you want to go with crit build instead. Poe is also an option for Phasma teams. GS for Phasma. Go Luke or GS for Poggle.

Long term you're looking at either:

Phasma, Dooku, GS, Lumi and Poe or QGJ or FOO. You could also throw Kylo in for Lumi or Dooku with this build.

Sid, Poggle, Luke, Lumi, Poe - that's the team I have and its top 3 on my server. Later on, you could add the droids if you wanted.

You may also want to finish JC, or get him to 6*. He's helpful, but mostly for GW.

Or you could try something totally new out
