I got my 5 star R2 and am setting up my team for 6/7 star while finishing out GMY and Thrawn. Who should I put on my team for R2? I have EP 7, Tarkin 6, Darth Vader 5. Should I level and up ability Thrawn at 5 now but 6/7 by the time I finish R2? Use TFP or RG? I have Mara but she's only 2 and not going up quickly any time soon... someone I'm overlooking?
