Im currently watching and enjoying the ahsoka show but my god they couldnt be more obvious that they are blatantly giving ahsoka plotlines and elements from the thrawn trilogy when it was originally meant to be for luke. Yes Thrawn was a major part of rebels plot but it was all pre OT timeline and could still be accepted.
Events of rise of thrawn during new republic era and defeating him were all something LUKE dealt with and not only they "decanonized" it they just copied elements from it and gave it to Dave's OC which is genuinely so annoying considering how awfully luke has been excluded and treated for majority of post disney SW media
They did the same with Rey new jedi order where we never got to see luke establishing new jedi order and training next generation of jedi while rey will be shown as next Jedi master legend in future sequel period media. Yes luke's students all get wiped out in sequels but it'd still be nice to see the brief period where things were going well
Again, I dont dislike the ahsoka show, or the new post empire timeline events intorduced in post disney - CW. I just hate that majority of their "new" ideas are just taking luke's acheivements and giving them to other characters.
I wouldnt have minded an ahsoka trilogy where ahsoka had to deal with new and unique threats which develop her character but being so blatant about the whole thrawn thing being Ahsoka's quest just seems like they're mocking Luke fans by saying "Forget luke, Ahsoka is the new face of SW and is much better suited for saving the galaxy from big threats while luke makes grogu choose between chainmail and jedi lightsaber"
I know to keep my expectations low for him appearing during Ahsoka season 2 or any events of this timeline but it'd be really a huge plot hole and insult to his character to not involve him to deal with Thrawn at all.
