I would have preferred Maul stay dead too. I think they could have kept Savage as Dooku's apprentice for longer than one arc. Then Savage goes his own way, proves himself to be intelligent, works with Death Watch and begins to be his own power. Sidious goes to Mandalore, confronts him one on one, smacks him down before telling him the same "I'm not going to kill you, I have other uses for you." I think they could have done more with the plot point that Dooku wanted to overthrow Palpatine with Savage, while Palpatine defeats Savage and uses him to his own ends. I liked the Nightsisters arc, but I was kind of disappointed at how quickly they dropped the matter of Dooku wanting to overthrow Palpatine. Also that Palpatine personally deals with Savage with it never coming to Palpatine's attention that Savage was Dooku's failed attempt at taking an apprentice, because Maul is back in the picture and distracts from it. I would be interested to know if the Maul comic will at all address this and show that Palpatine knew or didn't know of Dooku's attempted betrayal. We keep hearing about Sith betrayal, and even Darth Bane says to Yoda that "you must kill me, if you want my place." So alternatively, I could have accepted Maul surviving and serving as a mentor to Savage and teaching him the ways of the Sith, but I would have liked to have seen this betrayal followed through to its conclusion at least once in TCW. That perhaps Savage finds Maul in seclusion, is trained in the Dark Side in a similar situation to which Luke is trained by Yoda (where Yoda is in hiding and nobody knows of his presence there). With perhaps Maul using Savage, thinking that he's going to reveal himself to the galaxy again and be a force to be reckoned with, but only for Savage to learn everything Maul could teach him, and then kill Maul. Or option three. I think they could have done everything exactly as had occurred. But merely switched Maul and Savage's deaths. Where Maul keeps slapping Savage down and asserts that he is the master and Savage is the apprentice. Only for Sidious to sense Savage's Force potential, kill Maul, and then disarm Savage and tell him that he has other uses for him. But in any event, I think there was more potential for Savage's story after the Nightsister's arc, which was disappointingly dropped once Maul was re-introduced.
