I agree completely, it just ended and season 6 didn't tie up any loose ends what so ever. I'd love for CW to come back, and like you said it always had an ending with ROTS. Honestly I find myself missing a lot of the characters, especially after reading Dark Disciple I miss Asajj haha.The weird part about Clone Wars is that it always had a bit of a built in finale with Revenge of the Sith. Sure, Rex, Ahsoka, and Asajj and a few others were question marks as to where they would end up but everyone else was already a done deal. And with Rebels some of those are looking to be wrapped up and answered too.
I find myself wanting more episodes less for closure and simply because, like a good television series, the stories of Clone Wars did such a good job of suggesting even more stories.
It's a shame that (so far at least) those last episodes couldn't get finished off for more Netflix content. Binging is the perfect format for those long four part story arcs.
