Agreed completely...that's the primary reason for this new character. They can't show Vader failing to defeat this band of rebels for the entire run of the series. That would take away from his mystique.
Also, I'd love to see Ahsoka pop up on this show, and I too believe she will. I'm not sure we'll get the duel, but I can't imagine her not showing up eventually.
