I loved Ahsoka in Clone Wars and Rebels. Some how, she has completely lost her personality and rebellious nature. She must be drinking the Disney Koolaide!
Also, Hera was a much stronger person in Rebels. Now that she's General, she just follows orders and flies the ship... Did she have some Koolaide too?
So far, Sabine is acting according to character. Not sure if that's enough to keep me interested.
Maybe if Ahsoka stopped folding her arms and mumbling, her real personality would come back. In Clone Wars, there was no boredom.
