I do have Padme at R7, along with GK R7, C3PO R5, Ashoka R5. I avoided GAS for one reason: to keep Padme at high enough stamina in case I need her. My win ratio with Padme against GAS squad is around 50-50 as I never really geared up JKA or other fifth GR toons beyond G12 yet.
CLS is more of a soft counter against GAS.
And I collected the top crate rewards last night. Ironically it was Padme who helped to grab the 20 attacks out of turns feat against SEE (I need 2 more key cards to reach it.)
Thanks for making an assumption though.
