Are you sure you didn't get this idea from Sesslar's Something? Because he just did a video asking this exact same question, and he summed up my feelings on prequels pretty well. The sense of mystery tends to be lacking from prequels. Now, there are certainly exceptions, and many of them, but a lot of the time the ultimate question of "does this person live or die?" is missing from a prequel. The reason being, of course, because of the fact that if the person is still around in the original, then they can't die. You could put the character in the most hopeless, dangerous, no-way-he's-getting-out-of-this-one situation, but it won't matter because that character can't die.
This is the main reason I stay far away from ANY Star Wars book that is written during the "Prequel" Era. I don't care how good it is, I simply can't find the strength to make myself care. Knowing that the vast majority of these characters will all be dead in a few years just kills any interest I have in their stories. On the flip side, I have read nearly every book that takes place AFTER Return of the Jedi (and several that take place in between the original movies) because those characters' fates have not been decided yet.
That's the only real reason I watch The Clone Wars. Ahsoka's fate is an unknown. She's never mentioned (that's another thing that drives me nuts about prequels--new, important characters who are never mentioned in the originals) and we have no idea what happens to her. So the mystery is still around her. Now if only the writers would actually write about her and stop making her a secondary character next to Anakin and Obi.
