The curse of fans writing material is that they tend to regurgitate the cool beats from the original source material. If Vader's going to be engaging these characters directly, there's going to have to be a novel twist. Or he just kills them, which I doubt.
Well, I don't see too many opportunities for Vader to be engaging the heroes directly, with any regularity ... though I also don't see where anyone here is advocating specifically that kind of interaction, either. Furthermore, Filoni and his crew made quite a bit of hay out of referencing specific beats, lines, circumstances, etc. in
TCW. Whether or not you think they were simply "regurgitating" those moments, or utilizing them in a fun way to advance the story
and refer back to all six films in the saga is, certainly, open to interpretation.
But as far as I am concerned, they handled those references exceedingly well. To the point where I have little concern that depicting Vader on-screen in
Rebels would undermine his character or the OT.
I could have done with fewer direct confrontations with Grievous. Grievous was established in the micro-series as a badass who could take out Jedi Masters. His lightsaber collection was earned. In some cases, that carried over into TCW, but in others not so much and in eye-rolling fashion. Ahsoka, having survived at least two direct confrontations with Grievous, is by implication one of the most skilled Jedi in the galaxy. Fortunately, at least in my book, she lived up to that distinction in the final episodes of season five.
This confrontation between Ahsoka and Grievous was pretty good:

Unfortunately, this one, the first, was much less so. Obviously, the writers hadn't yet seen
The Incredibles, or they'd've learned the pitfalls of monologuing (

In other words, Leia aboard the Death Star all over again, only before Leia aboard the Death Star ever happens. Yeah, I hope the writers don't pen some episode where Vader has the crew in his sights, captures one or more of them and then we sit back and watch the incompetence of his supposed crack troops as the characters escape or get rescued. Then there's the obligatory "Vader balling up his fist and complaining" scene where he vows to destroy them all should their paths cross again.
Not too enthusiastic about that. They could do better, and the fewer "whew, that was a close call" encounters with Darth Vader the better for everybody.
Yeah, that scenario seems like a temptation. Some heroes are captured, but kept alive, because they have to be interrogated, which—wait for it—creates the opportunity for escape. Lucas already went there in the OT right out of the gate, and even covered the trope of the bad guys letting the heroes escape just to track them back to base. Next film, some heroes were captured to be used as bait to lure another. The
Rebels writers are going to have to be really creative to come up with something to top ANH and TESB, if they are going to revisit the captured heroes trope, but it will still have the handicap of occurring chronologically before the OT, which risks undermining the OT. Best not to go there at all, and instead come up with something fundamentally new, especially if Vader is involved.*
* - Another temptation (gods, I can see it now): They decide to "explain" how it is that Vader knows in ANH that Obi-Wan isn't planning to escape, by having
Rebels characters employ a similar gambit on Vader. See, Vader knows, because he's seen it before! Get it?
However, all six films in the PT and OT have involved rescues of main characters (Queen Amidala by Qui-Gon & Obi-Wan; Obi-Wan by Anakin & Padmé & Mace & Yoda; Palpatine by Obi-Wan and Anakin; Leia by everybody else but losing Obi-Wan; everybody else except R2 by Luke but failing to rescue Han; Han & Leia by the Ewoks), so maybe captures and rescues are obligatory in
Star Wars.
I'm with you on wanting to see more politics and the development of the Empire into the institution we saw for the very first time in A New Hope. I'd like to see the Senate chamber in action all over again, this time as the Imperial Senate. Some Imperial bureaucrats and moffs rushing about trying to determine which official gets to rule which sliver or chunk of territory and how it will benefit them and their own ambitions.
I know this is an animated show on a Disney network that skews towards kids, boys and action, but some texture and depth won't hurt a series like this. Given all the kid-friendly elements in Episode I we still got treated to a lot of political jockeying and terminology, so I hope the new show takes a similar route.
Political machinations would be nice. I hope there are at least a few episodes spotlighting that. One of my favorite scenes in
Star Wars is the first scene aboard the
Death Star.
