So, I'll add to this.
I've watched singular episodes of CW and Rebels - completely in passing and that's it.
Trying to get my kid to watch that instead of Bey Blade (barf)...
Anyways, someone called out that the HK droids had Thrawn's 3rd Fleet (or w/e) insignia on their head. I mean that is an Easter egg 100%, and only pays homage to fan-boys, BUT it doesn't take away from my enjoyment of the show.
As I said, since I am not familiar with either animated series, the magistrates skill with a staff led me to believe that she was more than she seemed. Hence, why I said maybe she was supposed to represent something like an inquisitor or other semi-force sensitive bad guy. (I think inquisitors are force sensitive and good combatants - right?)
All this to say, I like the series and like the nods to other things in the SW universe, I don't feel it detracts from the show by not being familiar with these things, but I would say those of you that are familiar, probably get a little bit more enjoyment out of somethings. That said, don't come crying when something changes...
