As a long time Clone Wars fan… I agree. It’s clear Filoni is way to attached to these characters. Just kill Ahsoka off already, it’s already asking much to have her survive into Rebels, but now she was the most highly qualified Jedi through the OT? So much for Luke.
Watch, they’re gonna retcon in Ahsoka to train Luke in between ESB and ROTJ and force a fake relationship a la Rey and Leia, thus nullifying any impact of Yoda.
