Should I swap to a scoundrel team for arena? (And questions about my current arena team)

At lvl 64 lumi is fine. By 75 to 80, lumi will not be hot.

Ben lead is fine. But ep will eventually make ben lead pretty miserable.

Scoundrels? Sure. As long as lando and St han are the first ones on the bus. Ig88 next. U already got leia, so u can add ackbar and biggs eventually for the next palp event. EP is a huge part of the meta, and u don't wanna miss out when that comes back..

RG, yes. RG and ST Han should be on every f2p roster sooner rather than later.

Things have changed so much..... a month ago I would say u should just farm st han and rey and ur set.
