Droids just don't do it right now. Yes, if maxed with Poe 7* or RG 7* it can land you top 50 and 20 on a good day. What you lack is speed damage in your squad. Once you finish fives, go for QGJ and once 5* and maxed in every other way, put him in as your leader. Continue with GS until he's maxed. Then you can run QGJ (L), lumi, GS, and then your choice of 86, poggle, fives, Sid and phasma for the last 2 spots. I'd go with poggle and fives or phasma becuase it will mean that everyone should get their first turn without being OHKO by anyone. One thing you do lack is a bit of control in terms of stuns. It will be worthwhile going for dooku after GS, and then bring him into the team becuase it will mean you'll do better against Jedi, and you'll be able to leave him as your leader on defence knowing full well that he will frustrate all enemies.
