So I just got Luke up to 6 stars earlier. My current arena team is Sid/lumi/Luke/Poe and JC for lack of a better option. I am currently shipment farming Poe/Sid/Lumi. U guys think I should go ahead and grind Luke to 7 stars or switch it up and go for someone else? Other options I considered who I already have are 1* geo, 2* Biggs, 4* JC, or go get Finn or Kylo. I am lvl 53 btw so that limits me to the first 4 cantina levels. Lemme know what u guys think.
